Wireless ADSL2/2+ Modem Router Features
The Wireless ADSL2/2+ Modem Router incorporates many advanced features, care-
fully designed to provide sophisticated functions while being easy to use.
Internet Access Features
•
Shared Internet Access. All users on the LAN or WLAN can access the
Internet through the Wireless ADSL2/2+ Modem Router, using only a single ex-
ternal IP Address. The local (invalid) IP Addresses are hidden from external
sources. This process is called NAT (Network Address Translation).
•
•

Introduction
•
Fixed or Dynamic IP Address. On the Internet (ADSL port) connection, the
Wireless ADSL2/2+ Modem Router supports both Dynamic IP Address (IP Ad-
dress is allocated on connection) and Fixed IP Address.
Advanced Internet Functions
•
Application Level Gateways (ALGs). Applications which use non-standard
connections or port numbers are normally blocked by the Firewall. The ability to
define and allow such applications is provided, to enable such applications to be
used normally.
•
Special Applications. This feature, also called Port Triggering, allows you to
use Internet applications which normally do not function when used behind a fire-
wall.
•
•
Virtual Servers. This feature allows Internet users to access Internet servers
on your LAN. The required setup is quick and easy.
Dynamic DNS Support. DDNS, when used with the Virtual Servers feature,
allows users to connect to Servers on your LAN using a Domain Name, even if
you have a dynamic IP address which changes every time you connect.
•
•
URL Filter. Use the URL Filter to block access to undesirable Web sites by LAN
users.
Firewall. As well as the built-in firewall to protect your LAN, you can define
Firewall Rules to determine which incoming and outgoing traffic should be permit-
ted.
•
Scheduling. Both the URL Filter and Firewall rules can be scheduled to operate
only at certain times. This provides great flexibility in controlling Internet -bound
traffic.
•
•
Logs. Define what data is recorded in the Logs, and optionally send log data to a
Syslog Server. Log data can also be E-mailed to you.
VPN Pass through Support. PCs with VPN (Virtual Private Networking)
software using PPTP, L2TP and IPSec are transparently supported - no configura-
tion is required.
VPN Features
•
•
IPSec Support. IPSec is the most common protocol.
Easy Configuration. The configuration required to allow 2 Wireless ADSL2/2+
Modem Routers to establish a VPN connection between them is easy accom-
plished.
Wireless Features
•
Standards Compliant. The Wireless ADSL2/2+ Modem Router complies with
the IEEE802.11g (DSSS) specifications for Wireless LANs.
•
Supports both 802.11b and 802.11g Wireless Stations. The 802.11g
standard provides for backward compatibility with the 802.11b standard, so both
802.11b and 802.11g Wireless stations can be used simultaneously.
•
•
Speeds to 54Mbps. All speeds up to the 802.11g maximum of 54Mbps are
supported.
WEP support. Support for WEP (Wired Equivalent Privacy) is included. Key
sizes of 64 Bit and 128 Bit are supported. WEP encrypts any data before trans-
mission, providing protection against snoopers.

Wireless ADSL2/2+ Modem Router User Guide
•
•
•
WPA-PSK support. Like WEP, WPA-PSK encrypts any data before transmis-
sion, providing protection against snoopers. The WPA-PSK is a later standard
than WEP, and provides both easier configuration and greater security than WEP.
Wireless MAC Access Control. The Wireless Access Control feature can
check the MAC address (hardware address) of Wireless stations to ensure that
only trusted Wireless Stations can access your LAN.
Simple Configuration. If the default settings are unsuitable, they can be
changed quickly and easily.
LAN Features
•
4-Port Switching Hub. The Wireless ADSL2/2+ Modem Router incorporates a
4-port 10/100BaseT switching hub, making it easy to create or extend your LAN.
•
DHCP Server Support. Dynamic Host Configuration Protocol provides a
dynamic IP address to PCs and other devices upon request. The Wireless
ADSL2/2+ Modem Router can act as a DHCP Server for devices on your local
LAN and WLAN.
Configuration & Management
•
Easy Setup. Use your WEB browser from anywhere on the LAN or WLAN for
configuration.
•
Configuration File Upload/Download. Save (download) the configuration
data from the Wireless ADSL2/2+ Modem Router to your PC, and restore (upload)
a previously-saved configuration file to the Wireless ADSL2/2+ Modem Router.
•
•
Remote Management. The Wireless ADSL2/2+ Modem Router can be man-
aged from any PC on your LAN or Wireless LAN. And, if the Internet connection
exists, it can also (optionally) be configured via the Internet.
Network Diagnostics. You can use the Wireless ADSL2/2+ Modem Router to
perform a Ping or DNS lookup.
Security Features
•
Password - protected Configuration. Password protection is provided to
prevent unauthorized users from modifying the configuration data and settings.
•
Wireless LAN Security. WPA-PSK, WEP and Wireless access control by
MAC address are all supported. The MAC-level access control feature can be
used to prevent unknown wireless stations from accessing your LAN.
•
NAT Protection. An intrinsic side effect of NAT (Network Address Translation)
technology is that by allowing all LAN users to share a single IP address, the loca-
tion and even the existence of each PC is hidden. From the external viewpoint,
there is no network, only a single device - the Wireless ADSL2/2+ Modem Router.
•
•
Firewall. All incoming data packets are monitored and all incoming server re-
quests are filtered, thus protecting your network from malicious attacks from
external sources.
Protection against DoS attacks. DoS (Denial of Service) attacks can flood
your Internet connection with invalid packets and connection requests, using so
much bandwidth and so many resources that Internet access becomes unavail-
able. The Wireless ADSL2/2+ Modem Router incorporates protection against DoS
attacks.

•
If Enabled, the Wireless ADSL2/2+ Modem Router will
allocate IP Addresses to PCs (DHCP clients) on your LAN
when they start up. The default (and recommended) value is
Enabled.
•
If you are already using a DHCP Server, this setting must be
Disabled, and the existing DHCP server must be re-
configured to treat the Wireless ADSL2/2+ Modem Router
as the default Gateway. See the following section for further
details.
•

DHCP
What DHCP Does
A DHCP (Dynamic Host Configuration Protocol) Server allocates a valid IP address to
a DHCP Client (PC or device) upon request.
•
•
The client request is made when the client device starts up (boots).
The DHCP Server provides the Gateway and DNS addresses to the client, as well
as allocating an IP Address.
•
•
The Wireless ADSL2/2+ Modem Router can act as a DHCP server.
Windows 95/98/ME and other non-Server versions of Windows will act as a DHCP
client. This is the default Windows setting for the TCP/IP network protocol. How-
ever, Windows uses the term Obtain an IP Address automatically instead of
"DHCP Client".
•
You must NOT have two (2) or more DHCP Servers on the same LAN segment.
(If your LAN does not have other Routers, this means there must only be one (1)
DHCP Server on your LAN.)
Using the Wireless ADSL2/2+ Modem Router's DHCP Server
This is the default setting. The DHCP Server settings are on the LAN screen. On this
screen, you can:
•
•
Enable or Disable the Wireless ADSL2/2+ Modem Router's DHCP Server function.
Set the range of IP Addresses allocated to PCs by the DHCP Server function.
You can assign Fixed IP Addresses to some devices
while using DHCP, provided that the Fixed IP Addresses
are NOT within the range used by the DHCP Server.
Using another DHCP Server
You can only use one (1) DHCP Server per LAN segment. If you wish to use another
DHCP Server, rather than the Wireless ADSL2/2+ Modem Router's, the following
procedure is required.
•
Disable the DHCP Server feature in the Wireless ADSL2/2+ Modem Router. This
setting is on the LAN screen.
•
Configure the DHCP Server to provide the Wireless ADSL2/2+ Modem Router's
IP Address as the Default Gateway.
To Configure your PCs to use DHCP
This is the default setting for TCP/IP for all non-Server versions of Windows.
See Chapter 4 - Client Configuration for the procedure to check these settings.

Wireless Security
This screen is accessed by clicking the "Configure" button on the Wireless screen.
There are 3 options for Wireless security:
•
•
•
Disabled - no data encryption is used.
WEP - data is encrypted using the WEP standard.
WPA-PSK - data is encrypted using the WPA-PSK standard. This is a later stan-
dard than WEP, and provides much better security than WEP. If all your Wireless
stations support WPA-PSK, you should use WPA-PSK rather than WEP.
WEP Wireless Security

Select the desired option, and ensure the Wireless Stations use
the same setting.
WEP Data
Encryption
•
64 Bit - data is encrypted, using the default key, before
being transmitted. You must enter at least the default key.
For 64 Bit Encryption, the key size is 10 chars in HEX (0~9
and A~F).
•
128 Bit - data is encrypted, using the default key, before
being transmitted. You must enter at least the default key.
For 128 Bit Encryption, the key size is 26 chars in HEX (0~9
and A~F).
Normally, this should be left at the default value of "Automatic".
If changed to "Open System" or "Shared Key", ensure that your
Wireless Stations use the same setting.

Like WEP, data is encrypted before transmission. WPA is
more secure than WEP, and should be used if possible. WPA-
PSK is the version of WPA, which does NOT require a Radius
Server on your LAN.
Enter the PSK (network key). Data is encrypted using a key
derived from the network key. Other Wireless Stations must
use the same network key. The PSK must be from 8 to 63
characters in length.

DHCP Server, providing an IP address and related information
to all Wireless and LAN users.
Modem - Only the ADSL Modem component is operational. All
Router features are disabled. This device is "transparent" - it
does not perform any operations or make any changes to the
network traffic passing through it. You need to have a DHCP
Server on your LAN to provide IP addresses to the Wireless cli-
ents using this Access Point.

The Wireless Access Point can function in either Router or Modem mode. But
generally it is not a good idea to combine a Modem with an Access Point, be-
cause all data received from the wireless stations will be sent over the modem
connection. (Since the modem is transparent, it does not examine the traffic to de-
termine whether the traffic is for the LAN or the WAN.)

Overview
For each PC, the following may need to be configured:
•
•
•
TCP/IP network settings
Internet Access configuration
Wireless configuration
Windows Clients
This section describes how to configure Windows clients for Internet access via the
Wireless ADSL2/2+ Modem Router.
The first step is to check the PC's TCP/IP settings.
The Wireless ADSL2/2+ Modem Router uses the TCP/IP network protocol for all
functions, so it is essential that the TCP/IP protocol be installed and configured on
each PC.
TCP/IP Settings - Overview
If using the default Wireless ADSL2/2+ Modem Router settings, and the
default Windows TCP/IP settings, no changes need to be made.
•
•
By default, the Wireless ADSL2/2+ Modem Router will act as a DHCP Server,
automatically providing a suitable IP Address (and related information) to each PC
when the PC boots.
For all non-Server versions of Windows, the default TCP/IP setting is to act as a
DHCP client.
If using a Fixed (specified) IP address, the following changes are re-
quired:
•
The Gateway must be set to the IP address of the Wireless ADSL2/2+ Modem
Router
•
The DNS should be set to the address provided by your ISP.
If your LAN has a Router, the LAN Administrator must re-
configure the Router itself. Refer to Chapter 8 - Ad-
vanced Setup for details.

DMZ
This feature, if enabled, allows the DMZ computer on your LAN to be exposed to all
users on the Internet.
•
•
•
This allows almost any application to be used on the "DMZ PC".
The "DMZ PC" will receive all "Unknown" connections and data.
If the DMZ feature is enabled, you must select the PC to be used as the "DMZ
PC".
The "DMZ PC" is effectively outside the Firewall, mak-
ing it more vulnerable to attacks. For this reason, you
should only enable the DMZ feature when required.
Special Applications
If you use Internet applications which use non-standard connections or port numbers,
you may find that they do not function correctly because they are blocked by the
Wireless Router's firewall. In this case, you can define the application as a "Special
Application".
The Special Applications screen can be reached by clicking the Special Applications
button on the Internet screen.
You can then define your Special Applications. You will need detailed information
about the application; this is normally available from the supplier of the application.
Also, note that the terms "Incoming" and "Outgoing" on this screen refer to traffic from
the client (PC) viewpoint

Using a Special Application
•
Configure the Special Applications screen as required.
•
On your PC, use the application normally. Remember that only one (1) PC can
use each Special application at any time. Also, when 1 PC is finished using a par-
ticular Special Application, there may need to be a "Time-out" before another PC
can use the same Special Application. The "Time-out" period may be up to 3 min-
utes.
URL Filter
If you want to limit access to certain sites on the Internet, you can use this feature.
The URL filter will check each Web site access. If the address, or part of the address,
is included in the block site list, access will be denied.
On the Advanced Internet screen, select the desired setting:

Dynamic DNS (Domain Name Server)
This free service is very useful when combined with the Virtual Server feature. It
allows Internet users to connect to your Virtual Servers using a URL, rather than an IP
Address.
This also solves the problem of having a dynamic IP address. With a dynamic IP
address, your IP address may change whenever you connect, which makes it difficult
to connect to you.
DDNS Services work as follows:
1. You must register for the service at one of the listed DDNS Service providers.
2. After registration, use the Service provider's normal procedure to obtain your
desired Domain name.
3. Enter your DDNS data on the Wireless ADSL2/2+ Modem Router's DDNS screen,
and enable the DDNS feature.
4. The Wireless ADSL2/2+ Modem Router will then automatically ensure that your
current IP Address is recorded at the DDNS service provider's Domain Name
Server.
5. From the Internet, users will be able to connect to your Virtual Servers (or DMZ
PC) using your Domain name, as shown on this screen.

Virtual Servers
This feature, sometimes called Port Forwarding, allows you to make Servers on your
LAN accessible to Internet users. Normally, Internet users would not be able to ac-
cess a server on your LAN because:
•
•
Your Server does not have a valid external IP Address.
Attempts to connect to devices on your LAN are blocked by the firewall in this
device.
The "Virtual Server" feature solves these problems and allows Internet users to con-
nect to your servers, as illustrated below.
Figure 56: Virtual Servers
IP Address seen by Internet Users
Note that, in this illustration, both Internet users are connecting to the same IP Ad-
dress, but using different protocols.
To Internet users, all virtual Servers on your LAN have the same IP Address.
This IP Address is allocated by your ISP.
This address should be static, rather than dynamic, to make it easier for Internet users
to connect to your Servers.
However, you can use the DDNS (Dynamic DNS) feature to allow users to connect to
your Virtual Servers using a URL, instead of an IP Address.

The "Virtual Servers" feature allows Internet Users to access PCs on your LAN.

For each entry, the PC must be running the appropri-
ate Server software.
If the desired Server type is not listed, you can define
your own Servers, using the Firewall Rules.
Connecting to the Virtual Servers
Once configured, anyone on the Internet can connect to your Virtual Servers. They
must use the Internet IP Address (the IP Address allocated to you by your ISP).
e.g.
http://203.70.212.52
ftp://203.70.212.52
It is more convenient if you are using a Fixed IP Address from your ISP, rather than
Dynamic. However, you can use the Dynamic DNS feature to allow users to connect
to your Virtual Servers using a URL, rather than an IP Address.

allows you to create a VPN connection between 2 Wireless ADSL2/2+ Modem
Routers, or a remote PC to establish a VPN connection to the Wireless ADSL2/2+
Modem Router.
To establish a VPN connection from a remote PC to the Wireless ADSL2/2+ Modem
Router, you need suitable (IPSec) VPN client software on your PC.
For more information about VPNs, please refer to Appendix C - About VPNs.
VPN Policies
A "VPN Policy" contains all the configuration data for a particular VPN connection.
Generally, you will have to create one policy for each site you wish to connect to. The
remote VPN Gateway (or client) needs to have matching configuration.
•
•
•
Traffic covered by an enabled policy will automatically be sent via a VPN tunnel. If
the VPN tunnel does not exist, it will be created.
The VPN tunnel is created according to the parameters in the SA (Security Asso-
ciation).
The remote VPN Endpoint must have a matching SA, or it will refuse the connec-
tion.
There are 2 types of VPN Policies:
•
Manual - All settings (including the keys) for the VPN tunnel are manually input at
each end (both VPN Endpoints).
•
Auto - Some parameters for the VPN tunnel are generated automatically. This
requires using the IKE (Internet Key Exchange) protocol to perform negotiations
between the 2 VPN Endpoints.

VPN Auto Policy Screen
This screen is displayed when you click the Add Auto Policy button on the VPN Poli-

"Auto" VPN policy.
An "Auto" VPN policy uses the IKE (Internet Key Protocol) to exchange and negotiate
parameters for the IPsec SA (Security Association). Because of this negotiation, it is
not necessary for all settings on this VPN Gateway to match the settings on the re-
mote VPN endpoint. Where settings must match, this is indicated.

SA Life Time
The key must be entered both here and on the remote VPN
Gateway. This method does not require using a CA (Certifi-
cate Authority).
This determines the time interval before the SA (Security
Association) expires. (It will automatically be re-established if
necessary.) While using a short time period (or data amount)
increases security, it also degrades performance. It is com-
mon to use periods over an hour (3600 seconds) for the SA
Life Time. This setting applies to both IKE and IPSec SAs.
If enabled, security is enhanced by ensuring that the key is
changed at regular intervals. Also, even if one key is broken,
subsequent keys are no easier to break. (Each key has no
relationship to the previous key.)
Enable PFS (Per-
fect Forward
Secrecy)
This setting applies to both IKE and IPSec SAs. When con-
figuring the remote endpoint to match this setting, you may
have to specify the "Key Group" used. For this device, the
"Key Group" is the same as the "DH Group" setting in the IKE
section.

PC Database
The PC Database is used whenever you need to select a PC (e.g. for the "DMZ" PC).
•
•
It eliminates the need to enter IP addresses.
Also, you do not need to use fixed IP addresses on your LAN.
However, if you do use a fixed IP address on some devices on your LAN, you should
enter details of each such device into the PC database, using the PC Database
screen.
PC Database Screen
An example PC Database screen is shown below.

•
•
PCs which are "DHCP Clients" are automatically added to the database, and
updated as required.
By default, non-Server versions of Windows act as "DHCP Clients"; this setting is
called "Obtain an IP Address automatically".
The Wireless ADSL2/2+ Modem Router uses the "Hardware Address" to identify
each PC, not the name or IP address. The "Hardware Address" can only change if
you change the PC's network card or adapter.
•
This system means you do NOT need to use Fixed (static) IP addresses on your
LAN. However, you can add PCs using Fixed (static) IP Addresses to the PC da-
tabase if required.

For security, you should restrict access to as few external IP
addresses as practical.
To connect from a remote PC via the Internet
1. Ensure your Internet connection is established, and start your Web Browser.
2. In the "Address" bar, enter "HTTP://" followed by the Internet IP Address of the
Wireless ADSL2/2+ Modem Router. If the port number is not 80, the port number
is also required. (After the IP Address, enter ":" followed by the port number.)
e.g.
HTTP://123.123.123.123:8080
This example assumes the WAN IP Address is 123.123.123.123, and the port
number is 8080.

Routing
Overview
•
•
•
If you don't have other Routers or Gateways on your LAN, you can ignore the
"Routing" page completely.
If the Wireless ADSL2/2+ Modem Router is only acting as a Gateway for the local
LAN segment, ignore the "Routing" page even if your LAN has other Routers.
If your LAN has a standard Router (e.g. Cisco) on your LAN, and the Wireless
ADSL2/2+ Modem Router is to act as a Gateway for all LAN segments, enable
RIP (Routing Information Protocol) and ignore the Static Routing table.
•
•
If your LAN has other Gateways and Routers, and you wish to control which LAN
segments use each Gateway, do NOT enable RIP (Routing Information Protocol).
Configure the Static Routing table instead. (You also need to configure the other
Routers.)
If using Windows 2000 Data center Server as a software Router, enable RIP on
the Wireless ADSL2/2+ Modem Router, and ensure the following Windows 2000
settings are correct:
•
•
Open Routing and Remote Access
In the console tree, select Routing and Remote Access , [server name], IP
Routing, RIP
•
•
In the "Details" pane, right-click the interface you want to configure for RIP
version 2, and then click "Properties".
On the "General" tab, set Outgoing packet protocol to "RIP version 2 broad-
cast", and Incoming packet protocol to "RIP version 1 and 2".
Routing Screen
The routing table is accessed by the Routing link on the Administration menu.
Using this Screen
Generally, you will use either RIP (Routing Information Protocol) OR the Static Rout-
ing Table, as explained above, although is it possible to use both methods
simultaneously.
Static Routing Table
•
If RIP is not used, an entry in the routing table is required for each LAN segment
on your Network, other than the segment to which this device is attached.
•
The other Routers must also be configured. See Configuring Other Routers on
your LAN later in this chapter for further details and an example.

Configuring Other Routers on your LAN
It is essential that all IP packets for devices not on the local LAN be passed to the
Wireless ADSL2/2+ Modem Router, so that they can be forwarded to the external LAN,
WAN, or Internet. To achieve this, the local LAN must be configured to use the Wire-
less ADSL2/2+ Modem Router as the Default Route or Default Gateway.

Advanced Administration
Local Router
The local router is the Router installed on the same LAN segment as the Wireless
ADSL2/2+ Modem Router. This router requires that the Default Route is the Wireless
ADSL2/2+ Modem Router itself. Typically, routers have a special entry for the Default
Route. It should be configured as follows.
Normally 0.0.0.0, but check your router documenta-
tion.

Other Routers on the Local LAN
Other routers on the local LAN must use the Wireless ADSL2/2+ Modem Router's
Local Router as the Default Route. The entries will be the same as the Wireless
ADSL2/2+ Modem Router's local router, with the exception of the Gateway IP Address.
•
For a router with a direct connection to the Wireless ADSL2/2+ Modem Router's
local Router, the Gateway IP Address is the address of the Wireless ADSL2/2+
Modem Router's local router.
•
For routers which must forward packets to another router before reaching the
Wireless ADSL2/2+ Modem Router's local router, the Gateway IP Address is the
address of the intermediate router.

Chapter 8
Modem Mode
8
This Chapter explains configuration and operation when in "Modem"
or "Bridge" mode..
Overview
There are two modes available on the Mode screen.
•
Router - Both the ADSL Modem and the Router features are operational. In this
mode, this device can provide shared Internet Access to all your LAN users. Also,
by default, it acts a DHCP Server, providing an IP address and related information
to all Wireless and LAN users.
•
Modem - Only the ADSL Modem component is operational. All Router features
are disabled. This device is "transparent" - it does not perform any operations or
make any changes to the network traffic passing through it. You need to have a
DHCP Server on your LAN to provide IP addresses to the Wireless clients using
this Access Point.
This Chapter describes operation while in Modem Mode, also called Bridge Mode.
Management Connections
When this device restarts in Modem mode, the IP address does not change, but the
DHCP server is disabled. However, your PC will usually retain the IP address pro-
vided by the DHCP Server, so the connection will be automatically re-established. You
then need to ensure that the IP address of this modem is suitable for your LAN.
•
You need to have a DHCP Server on your LAN to provide IP addresses to the
Wireless clients using this Access Point.
•
This Modem/AP must be a valid device on your LAN, to allow management con-
nections. You must assign a (fixed) IP address which is within the address range
used on your LAN, but not within the address range used by your DHCP server.
When you connect in future, just connect normally, using the IP address you assigned.
1. Start your WEB browser.
2. In the Address box, enter "HTTP://" and the current IP Address of the Wireless
ADSL Modem, as in this example, which uses the Wireless ADSL Modem's de-
fault IP Address:
HTTP://192.168.0.1
3. When prompted for the User name and Password, enter admin for the user name,
and the current password, as set on the password screen. (The password is the
same regardless of the mode.)

Appendix A
Troubleshooting
A
This Appendix covers the most likely problems and their solutions.
Overview
This chapter covers some common problems that may be encountered while using
the Wireless ADSL2/2+ Modem Router and some possible solutions to them. If you
follow the suggested steps and the Wireless ADSL2/2+ Modem Router still does not
function properly, contact your dealer for further advice.
General Problems
Problem 1: Can't connect to the Wireless ADSL2/2+ Modem Router to con-
figure it.
Check the following:
Solution 1:
•
The Wireless ADSL2/2+ Modem Router is properly installed, LAN
connections are OK, and it is powered ON.
•
Ensure that your PC and the Wireless ADSL2/2+ Modem Router
are on the same network segment. (If you don't have a router,
this must be the case.)
•
•
If your PC is set to "Obtain an IP Address automatically" (DHCP
client), restart it.
If your PC uses a Fixed (Static) IP address, ensure that it is using
an IP Address within the range 192.168.0.2 to 192.168.0.254 and
thus compatible with the Wireless ADSL2/2+ Modem Router's
default IP Address of 192.168.0.1.
Also, the Network Mask should be set to 255.255.255.0 to match
the Wireless ADSL2/2+ Modem Router.
In Windows, you can check these settings by using Control
Panel-Network to check the Properties for the TCP/IP protocol.
Internet Access
Problem 1: When I enter a URL or IP address I get a time out error.
A number of things could be causing this. Try the following trouble-
shooting steps.
Solution 1:
•
Check if other PCs work. If they do, ensure that your PCs IP
settings are correct. If using a Fixed (Static) IP Address, check
the Network Mask, Default gateway and DNS as well as the IP
Address.
•
If the PCs are configured correctly, but still not working, check
the Wireless ADSL2/2+ Modem Router. Ensure that it is con-
nected and ON. Connect to it and check its settings. (If you can't
connect to it, check the LAN and power connections.)

Wireless ADSL2/2+ Modem Router User Guide
•
Check the Wireless ADSL2/2+ Modem Router's status screen to
see if it is working correctly.
Problem 2: Some applications do not run properly when using the Wireless
ADSL2/2+ Modem Router.
The Wireless ADSL2/2+ Modem Router processes the data passing
through it, so it is not transparent.
Solution 2:
For incoming connections, you must use the Virtual Server or Fire-
wall Rules to specify the PC which will receive the incoming traffic.
You can also use the DMZ function. This should work with almost
every application, but:
•
•
It is a security risk, since the firewall is disabled.
Only one (1) PC can use this feature.
Wireless Access
Problem 1: My PC can't locate the Wireless Access Point.
Check the following.
Solution 1:
•
Your PC is set to Infrastructure Mode. (Access Points are always
in Infrastructure Mode)
•
The SSID on your PC and the Wireless Access Point are the
same.
Remember that the SSID is case-sensitive. So, for example
"Workgroup" does NOT match "workgroup".
•
Both your PC and the Wireless ADSL2/2+ Modem Router must
have the same setting for WEP. The default setting for the Wire-
less ADSL2/2+ Modem Router is disabled, so your wireless
station should also have WEP disabled.
•
•
If WEP is enabled on the Wireless ADSL2/2+ Modem Router,
your PC must have WEP enabled, and the key must match.
If the Wireless ADSL2/2+ Modem Router's Wireless screen is set
to Allow Trusted PCs only, then each of your Wireless stations
must have been designated as "Trusted", or the Wireless station
will be blocked.
•
To see if radio interference is causing a problem, see if connec-
tion is possible when close to the Wireless ADSL2/2+ Modem
Router.
Remember that the connection range can be as little as 100 feet
in poor environments.
Problem 2: Wireless connection speed is very slow.
The wireless system will connect at the highest possible speed,
depending on the distance and the environment. To obtain the high-
est possible connection speed, you can experiment with the
following:
Solution 2:
•
Wireless ADSL2/2+ Modem Router location.
Try adjusting the location and orientation of the Wireless
ADSL2/2+ Modem Router.
•
Wireless Channel
If interference is the problem, changing to another channel may

show a marked improvement.
•
•
Radio Interference
Other devices may be causing interference. You can experiment
by switching other devices Off, and see if this helps. Any "noisy"
devices should be shielded or relocated.
RF Shielding
Your environment may tend to block transmission between the
wireless stations. This will mean high access speed is only pos-
sible when close to the Wireless ADSL2/2+ Modem Router.

Appendix B
About Wireless LANs
B
This Appendix provides some background information about using
Wireless LANs (WLANs).
Modes
Wireless LANs can work in either of two (2) modes:
•
•
Ad-hoc
Infrastructure
Ad-hoc Mode
Ad-hoc mode does not require an Access Point or a wired (Ethernet) LAN. Wire-
less Stations (e.g. notebook PCs with wireless cards) communicate directly with
each other.
Infrastructure Mode
In Infrastructure Mode, one or more Access Points are used to connect Wireless
Stations (e.g. Notebook PCs with wireless cards) to a wired (Ethernet) LAN. The
Wireless Stations can then access all LAN resources.
Access Points can only function in "Infrastructure" mode,
and can communicate only with Wireless Stations which are
set to "Infrastructure" mode.
BSS/ESS
BSS
A group of Wireless Stations and a single Access Point, all using the same ID (SSID),
form a Basic Service Set (BSS).
Using the same SSID is essential. Devices with different SSIDs are unable to com-
municate with each other.
ESS
A group of Wireless Stations, and multiple Access Points, all using the same ID
(ESSID), form an Extended Service Set (ESS).
Different Access Points within an ESS can use different Channels. In fact, to reduce
interference, it is recommended that adjacent Access Points SHOULD use different
channels.
As Wireless Stations are physically moved through the area covered by an ESS, they
will automatically change to the Access Point which has the least interference or best

Appendix B - About Wireless LANs
performance. This capability is called Roaming. (Access Points do not have or require
Roaming capabilities.)
Channels
The Wireless Channel sets the radio frequency used for communication.
•
Access Points use a fixed Channel. You can select the Channel used. This allows
you to choose a Channel which provides the least interference and best perform-
ance. In the USA and Canada, 11 channels are available. If using multiple Access
Points, it is better if adjacent Access Points use different Channels to reduce inter-
ference.
•
•
In "Infrastructure" mode, Wireless Stations normally scan all Channels, looking for
an Access Point. If more than one Access Point can be used, the one with the
strongest signal is used. (This can only happen within an ESS.)
If using "Ad-hoc" mode (no Access Point), all Wireless stations should be set to
use the same Channel. However, most Wireless stations will still scan all Chan-
nels to see if there is an existing "Ad-hoc" group they can join.
WEP
WEP (Wired Equivalent Privacy) is a standard for encrypting data before it is transmit-
ted.
This is desirable because it is impossible to prevent snoopers from receiving any data
which is transmitted by your Wireless Stations. But if the data is encrypted, then it is
meaningless unless the receiver can decrypt it.
If WEP is used, the Wireless Stations and the Access Point must have the same
settings for each of the following:
Off, 64 Bit, 128 Bit
WEP
Key
For 64 Bit encryption, the Key value must match.
For 128 Bit encryption, the Key value must match
Open System or Shared Key.
WEP Authentication
WPA-PSK
WPA-PSK is another standard for encrypting data before it is transmitted. This is a
later standard than WEP (Wired Equivalent Privacy), and provides greater security for
your data. Data is encrypted using a 256Bit key which is automatically generated and
changed often.
If all your Wireless stations support WPA-PSK, you should use this instead of WEP.
If WPA-PSK is used, the Wireless Stations and the Access Point must have the
same settings for each of the following:
Enter the same value on every station and the AP.
The PSK must be from 8 to 63 characters in length.
The 256Bit key used for the actual encryption is de-
rived from this key.
WPA PSK

Wireless ADSL2/2+ Modem Router User Guide
The same encryption method must be used. The most
Encryption
common encryption method is TKIP. Another widely-
supported method is AES.
Wireless LAN Configuration
To allow Wireless Stations to use the Access Point, the Wireless Stations and the
Access Point must use the same settings, as follows:
On client Wireless Stations, the mode must be set to "Infrastruc-
ture".
Mode
(The Access Point is always in "Infrastructure" mode.)
Wireless Stations should use the same SSID (ESSID) as the
Access Point they wish to connect to. Alternatively, the SSID
can be set to "any" or null (blank) to allow connection to any
Access Point.
SSID (ESSID)
The Wireless Stations and the Access Point must use the same
settings for Wireless security. (None, WEP, WPA-PSK).
Wireless
Security
WEP: If WEP is used, the Key size (64Bit, 128Bit), Key value,
and Authentication settings must be the same on the Wireless
Stations and the Access Point.
WPA-PSK: If WPA-PSK is used, all Wireless Stations must be
set to use WPA-PSK, and have the same Pre-shared Key and
encryption system.
For Ad-hoc networks (no Access Point), all Wireless stations
must use the same security settings.

Appendix C
About VPNs
C
Overview
A VPN (Virtual Private Network) provides a secure connection between 2 points, over
an insecure network - typically the Internet. This secure connection is called a VPN
Tunnel.
There are many standards and protocols for VPNs. The standard implemented in the
Wireless ADSL2/2+ Modem Router is IPSec.
IPSec
IPSec is a near-ubiquitous VPN security standard, designed for use with TCP/IP
networks. It works at the packet level, and authenticates and encrypts all packets
traveling over the VPN Tunnel. Thus, it does not matter what applications are used on
your PC. Any application can use the VPN like any other network connection.
IPsec VPNs exchange information through logical connections called SAs (Security
Associations). An SA is simply a definition of the protocols, algorithms and keys used
between the two VPN devices (endpoints).
Each IPsec VPN has two SAs - one in each direction. If IKE (Internet Key Exchange)
is used to generate and exchange keys, there are also SA's for the IKE connection as
well as the IPsec connection.
There are two security modes possible with IPSec:
•
Transport Mode - the payload (data) part of the packet is encapsulated through
encryption but the IP header remains in the clear (unchanged).
The Wireless ADSL2/2+ Modem Router does NOT support Transport Mode.
•
Tunnel Mode - everything is encapsulated, including the original IP header, and a
new IP header is generated. Only the new header in the clear (i.e. not protected).
This system provides enhanced security.
The Wireless ADSL2/2+ Modem Router always uses Tunnel Mode.
IKE
IKE (Internet Key Exchange) is an optional, but widely used, component of IPsec. IKE
provides a method of negotiating and generating the keys and IDs required by IPSec.
If using IKE, only a single key is required to be provided during configuration. Also,
IKE supports using Certificates (provided by CAs - Certification Authorities) to au-
thenticate the identify of the remote user or gateway.
If IKE is NOT used, then all keys and IDs (SPIs) must be entered manually, and
Certificates can NOT be used. This is called a "Manual Key Exchange".
When using IKE, there are 2 phases to creating the VPN tunnel:
•
•
Phase I is the negotiation and establishment up of the IKE connection.
Phase II is the negotiation and establishment up of the IPsec connection.
Download from Www.Somanuals.com. All Manuals Search And Download.
Wireless ADSL2/2+ Modem Router User Guide
Because the IKE and IPsec connections are separate, they have different SAs (secu-
rity associations).
Policies
VPN configuration settings are stored in Policies.
Note that different vendors use different terms. Generally, the terms "VPN Policy",
"IPSec Policy", and "IPSec Proposal" have the same meaning. However, some ven-
dors separate IKE Policies (Phase 1 parameters) from IPSec Policies (Phase 2
parameters).
For the Wireless ADSL2/2+ Modem Router; each VPN policy contains both Phase 1
and Phase 2 parameters (if IKE is used). Each policy defines:
•
•
•
•
The address of the remote VPN endpoint
The traffic which is allowed to use the VPN connection.
The parameters (settings) for the IPsec SA (Security Association)
If IKE is used, the parameters (settings) for the IKE SA (Security Association)
Generally, you will need at least one (1) VPN Policy for each remote site for which you
wish to establish VPN connections.
It is possible, and sometimes necessary, to have multiple Policies for the same remote
site. However, you should only Enable one (1) policy at a time.
VPN Configuration
The general rule is that each endpoint must have matching Policies, as follows:
Each VPN endpoint must be configured to initiate or accept
connections to the remote VPN client or Gateway.
VPN Endpoint
address
Usually, this requires having a fixed Internet IP address. How-
ever, it is possible for a VPN Gateway to accept incoming
connections from a remote client where the client's IP address
is not known in advance.
This determines which outgoing traffic will cause a VPN connec-
tion to be established, and which incoming traffic will be
accepted. Each endpoint must be configured to pass and ac-
cept the desired traffic from the remote endpoint.
Local & Remote
LAN definition
If connecting 2 LANs, this requires that:
•
Each endpoint must be aware of the IP addresses used on
the other endpoint.
•
The 2 LANs MUST use different IP address ranges.
If using IKE (recommended), the IKE parameters must match
(except for the SA lifetime, which can be different).

Common VPN Situations
VPN Pass-through
Figure 76: VPN Pass-through
Here, a PC on the LAN behind the Router/Gateway is using VPN software, but the
Router/Gateway is NOT acting as a VPN endpoint. It is only allowing the VPN connec-
tion.
•
•
The PC software can use any VPN protocol supported by the remote VPN.
The remote VPN Server must support client PCs which are behind a NAT router,
and so have an IP address which is not valid on the Internet.
•
The Router/Gateway requires no VPN configuration, since it is not acting as a
VPN endpoint.
Client PC to VPN Gateway
Figure 77: Client PC to VPN Server
In this situation, the PC must run appropriate VPN client software in order to connect,
via the Internet, to the Wireless ADSL2/2+ Modem Router or other VPN Gateway.
Once connected, the client PC has the same access to LAN resources as PCs on the
local LAN (unless restricted by the network administrator).
•
IPsec is not the only protocol which can be used in this situation, but the Wireless
ADSL2/2+ Modem Router supports IPsec ONLY.
•
Windows 2000 and Windows XP include an IPsec VPN client program. However,
configuration of this client program for use with the Wireless ADSL2/2+ Modem
Router is very complex and beyond the scope of this document.

Connecting 2 LANs via VPN
Figure 78: Connecting 2 VPN Gateways
This allows two (2) LANs to be connected. PCs on each endpoint gain secure access
to the remote LAN.
•
•
The 2 LANs MUST use different IP address ranges.
The VPN Policies at each end determine when a VPN tunnel will be established,
and what systems on the remote LAN can be accessed once the VPN connection
is established.
•
It is possible to have simultaneous VPN connections to many remote sites.
VPN Example
In this example, 2 LANs are connected via VPN. Each end has a Wireless ADSL2/2+
Modem Router.

GNU GENERAL PUBLIC LICENSE
Version 2, June 1991
Copyright (C) 1989, 1991 Free Software Foundation, Inc.
59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
Everyone is permitted to copy and distribute verbatim copies of this license document,
but changing it is not allowed.
Preamble
The licenses for most software are designed to take away your freedom to share and
change it. By contrast, the GNU General Public License is intended to guarantee your
freedom to share and change free software--to make sure the software is free for all
its users. This General Public License applies to most of the Free Software Founda-
tion's software and to any other program whose authors commit to using it. (Some
other Free Software Foundation software is covered by the GNU Library General
Public License instead.) You can apply it to your programs, too.
When we speak of free software, we are referring to freedom, not price. Our General
Public Licenses are designed to make sure that you have the freedom to distribute
copies of free software (and charge for this service if you wish), that you receive
source code or can get it if you want it, that you can change the soft-ware or use
pieces of it in new free programs; and that you know you can do these things.
To protect your rights, we need to make restrictions that forbid anyone to deny you
these rights or to ask you to surrender the rights. These restrictions translate to cer-
tain responsibilities for you if you distribute copies of the software, or if you modify it.
For example, if you distribute copies of such a program, whether gratis or for a fee,
you must give the recipients all the rights that you have. You must make sure that they,
too, receive or can get the source code. And you must show them these terms so they
know their rights.
We protect your rights with two steps: (1) copyright the software, and (2) offer you this
license which gives you legal permission to copy, distribute and/or modify the software.
Also, for each author's protection and ours, we want to make certain that everyone
understands that there is no warranty for this free software. If the software is modified
by someone else and passed on, we want its recipients to know that what they have is
not the original, so that any problems introduced by others will not reflect on the
original authors' reputations.
Finally, any free program is threatened constantly by software patents. We wish to
avoid the danger that redistributors of a free program will individually obtain patent
licenses, in effect making the program proprietary. To prevent this, we have made it
clear that any patent must be licensed for everyone's free use or not licensed at all.
The precise terms and conditions for copying, distribution and modification follow.

GNU GENERAL PUBLIC LICENSE
Terms and Conditions For Copying, Distribution And Modification
0. This License applies to any program or other work which contains a notice placed
by the copyright holder saying it may be distributed under the terms of this General
Public License. The "Program", below, refers to any such program or work, and a
"work based on the Program" means either the Program or any derivative work under
copyright law: that is to say, a work containing the Program or a portion of it, either
verbatim or with modifications and/or translated into another language. (Hereinafter,
translation is included without limitation in the term "modification".) Each licensee is
addressed as "you".
Activities other than copying, distribution and modification are not covered by this
License; they are outside its scope. The act of running the Program is not restricted,
and the output from the Program is covered only if its contents constitute a work
based on the Program (independent of having been made by running the Program).
Whether that is true depends on what the Program does.
1. You may copy and distribute verbatim copies of the Program's source code as you
receive it, in any medium, provided that you conspicuously and appropriately publish
on each copy an appropriate copyright notice and disclaimer of warranty; keep intact
all the notices that refer to this License and to the absence of any warranty; and give
any other recipients of the Program a copy of this License along with the Program.
You may charge a fee for the physical act of transferring a copy, and you may at your
option offer warranty protection in exchange for a fee.
2. You may modify your copy or copies of the Program or any portion of it, thus form-
ing a work based on the Program, and copy and distribute such modifications or work
under the terms of Section 1 above, provided that you also meet all of these condi-
tions:
a) You must cause the modified files to carry prominent notices stating that you
changed the files and the date of any change.
b) You must cause any work that you distribute or publish, that in whole or in part
contains or is derived from the Program or any part thereof, to be licensed as a whole
at no charge to all third parties under the terms of this License.
c) If the modified program normally reads commands interactively when run, you must
cause it, when started running for such interactive use in the most ordinary way, to
print or display an announcement including an appropriate copyright notice and a
notice that there is no warranty (or else, saying that you provide a warranty) and that
users may redistribute the program under these conditions, and telling the user how to
view a copy of this License. (Exception: if the Program itself is interactive but does not
normally print such an announcement, your work based on the Program is not re-
quired to print an announcement.)
These requirements apply to the modified work as a whole. If identifiable sections of
that work are not derived from the Program, and can be reasonably considered inde-
pendent and separate works in themselves, then this License, and its terms, do not
apply to those sections when you distribute them as separate works. But when you
distribute the same sections as part of a whole which is a work based on the Program,
the distribution of the whole must be on the terms of this License, whose permissions
for other licensees extend to the entire whole, and thus to each and every part regard-
less of who wrote it. Thus, it is not the intent of this section to claim rights or contest
your rights to work written entirely by you; rather, the intent is to exercise the right to
control the distribution of derivative or collective works based on the Program.

Appendix D - Specifications
In addition, mere aggregation of another work not based on the Program with the
Program (or with a work based on the Program) on a volume of a storage or distribu-
tion medium does not bring the other work under the scope of this License.
3. You may copy and distribute the Program (or a work based on it, under Section 2)
in object code or executable form under the terms of Sections 1 and 2 above provided
that you also do one of the following:
a) Accompany it with the complete corresponding machine-readable source code,
which must be distributed under the terms of Sections 1 and 2 above on a medium
customarily used for software interchange; or,
b) Accompany it with a written offer, valid for at least three years, to give any third
party, for a charge no more than your cost of physically performing source distribution,
a complete machine-readable copy of the corresponding source code, to be distrib-
uted under the terms of Sections 1 and 2 above on a medium customarily used for
software interchange; or,
c) Accompany it with the information you received as to the offer to distribute corre-
sponding source code. (This alternative is allowed only for noncommercial distribution
and only if you received the program in object code or executable form with such an
offer, in accord with Subsection b above.)
The source code for a work means the preferred form of the work for making modifica-
tions to it. For an executable work, complete source code means all the source code
for all modules it contains, plus any associated interface definition files, plus the
scripts used to control compilation and installation of the executable. However, as a
special exception, the source code distributed need not include anything that is nor-
mally distributed (in either source or binary form) with the major components (compiler,
kernel, and so on) of the operating system on which the executable runs, unless that
component itself accompanies the executable.
If distribution of executable or object code is made by offering access to copy from a
designated place, then offering equivalent access to copy the source code from the
same place counts as distribution of the source code, even though third parties are
not compelled to copy the source along with the object code.
4. You may not copy, modify, sublicense, or distribute the Program except as ex-
pressly provided under this License. Any attempt otherwise to copy, modify,
sublicense or distribute the Program is void, and will automatically terminate your
rights under this License. However, parties who have received copies, or rights, from
you under this License will not have their licenses terminated so long as such parties
remain in full compliance.
5. You are not required to accept this License, since you have not signed it. However,
nothing else grants you permission to modify or distribute the Program or its derivative
works. These actions are prohibited by law if you do not accept this License. There-
fore, by modifying or distributing the Program (or any work based on the Program),
you indicate your acceptance of this License to do so, and all its terms and condi-tions
for copying, distributing or modifying the Program or works based on it.
6. Each time you redistribute the Program (or any work based on the Program), the
recipient automatically receives a license from the original licensor to copy, distribute
or modify the Program subject to these terms and conditions. You may not impose
any further restrictions on the recipients' exercise of the rights granted herein. You are
not responsible for enforcing compliance by third parties to this License.
7. If, as a consequence of a court judgment or allegation of patent infringement or for
any other reason (not limited to patent issues), conditions are imposed on you
(whether by court order, agreement or otherwise) that contradict the conditions of this
License, they do not excuse you from the conditions of this License. If you cannot

Wireless ADSL2/2+ Modem Router User Guide
distribute so as to satisfy simultaneously your obligations under this License and any
other pertinent obligations, then as a consequence you may not distribute the Pro-
gram at all. For example, if a patent license would not permit royalty-free redistribution
of the Program by all those who receive copies directly or indirectly through you, then
the only way you could satisfy both it and this License would be to refrain entirely from
distribution of the Program.
If any portion of this section is held invalid or unenforceable under any particular
circumstance, the balance of the section is intended to apply and the section as a
whole is intended to apply in other circumstances.
It is not the purpose of this section to induce you to infringe any patents or other
property right claims or to contest validity of any such claims; this section has the sole
purpose of protecting the integrity of the free software distribution system, which is
implemented by public license practices. Many people have made generous contribu-
tions to the wide range of software distributed through that system in reliance on
consis-tent application of that system; it is up to the author/donor to decide if he or she
is willing to distribute software through any other system and a licensee cannot im-
pose that choice.
This section is intended to make thoroughly clear what is believed to be a conse-
quence of the rest of this License.
8. If the distribution and/or use of the Program is restricted in certain countries either
by patents or by copyrighted interfaces, the original copyright holder who places the
Program under this License may add an explicit geographical distribution limitation
excluding those countries, so that distribution is permitted only in or among countries
not thus excluded. In such case, this License incorporates the limitation as if written in
the body of this License.
9. The Free Software Foundation may publish revised and/or new versions of the
General Public License from time to time. Such new versions will be similar in spirit to
the present version, but may differ in detail to address new problems or concerns.
Each version is given a distinguishing version number. If the Program specifies a
version number of this License which applies to it and "any later version", you have
the option of following the terms and condi-tions either of that version or of any later
version published by the Free Software Foundation. If the Program does not specify a
version number of this License, you may choose any version ever published by the
Free Software Foundation.
10. If you wish to incorporate parts of the Program into other free programs whose
distribution conditions are different, write to the author to ask for permission. For
software which is copyrighted by the Free Software Foundation, write to the Free
Software Foundation; we sometimes make exceptions for this. Our decision will be
guided by the two goals of preserving the free status of all derivatives of our free
software and of promoting the sharing and reuse of software generally.

NO WARRANTY
11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO
WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE
COPYRIGHT HOLDERS AND/OR OTHER PARTIES
PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER
EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED
WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF
THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE,
YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
REPAIR OR CORRECTION.
12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY
MODIFY AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE
LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL,
INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR
INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH
ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS
BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
