Wireless Placement and Range Guidelines
The range of your wireless connection can vary significantly based on the physical placement of
the wireless voice gateway. The latency, data throughput performance, and notebook power
consumption of wireless adapters also vary depending on your configuration choices.
For best results, place your wireless voice gateway:
•
•
Near the center of the area in which your PCs will operate.
In an elevated location such as a high shelf where the wirelessly connected PCs have line-of-
sight access (even if through walls).

•
Away from sources of interference, such as PCs, microwave ovens, and 2.4 GHz cordless
phones.
•
•
Away from large metal surfaces.
Put the antenna in a vertical position to provide the best side-to-side coverage. Put the antenna
in a horizontal position to provide the best up-and-down coverage.
•
If using multiple access points, it is better if adjacent access points use different radio
frequency channels to reduce interference. The recommended channel spacing between
adjacent access points is 5 channels (for example, use channels 1 and 6, or 6 and 11).
The time it takes to establish a wireless connection can vary depending on both your security
settings and placement. WEP connections can take slightly longer to establish. Also, WEP
encryption can consume more battery power on a notebook computer.

Understanding Wireless Security Options
Wireless data transmissions can be received well beyond your walls by anyone with a compatible
adapter. For this reason, use the security features of your wireless equipment. For more
information about wireless security, see the link “Wireless Communications:” in Appendix B.
Deploy the security features appropriate to your needs.
There are several ways you can enhance the security of your wireless network:
•
MAC access list (Wireless Card Access). You can restrict access to only trusted PCs so that
unknown PCs cannot wirelessly connect to the gateway. This adds an obstacle against
unwanted access to your network, but the data broadcast over the wireless link is fully
exposed.
•
•
•
Use WEP. Wired Equivalent Privacy (WEP) data encryption provides data security. WEP
Shared Key authentication and WEP data encryption will block all but the most determined
eavesdropper.
Use WPA, WPA-PSK or WPA2-PSK. Wi-Fi Protected Access (WPA) data encryption
provides data security. The very strong authentication along with dynamic per frame rekeying
of WPA makes it virtually impossible to compromise.
Turn Off the Broadcast of the Wireless Network Name (SSID). If you disable broadcast of
the SSID, only devices that have the correct SSID can connect. This nullifies the wireless
network “discovery” feature of some products such as Windows XP, but the data is still fully
exposed to a determined snoop using specialized test equipment like wireless sniffers.
Configuring Wireless Settings
To configure the wireless settings:
1. Connect a computer to the wireless voice gateway using an Ethernet or USB cable as
described in “Connecting the Wireless Voice Gateway” on page 1-5.

change the channel if there is interference (shown by lost connections and/or slow data
transfers).
•
•

computers on the network can access the Internet. The default is enabled.
wireless stations. Stations with no SSID (or a “null” value) can use the SSID to connect to
this access point. The default is enabled.
•
Wireless Card Access List: You can use an Access List to increase security for the
wireless network. The Access List includes the MAC addresses of PCs that are allowed to
connect. The default is disabled. If you enable this feature, see “Configuring Your
Wireless Card Access List” on page 2-11.

Chapter 3
Protecting Your Network
This chapter describes how to use the firewall features of the gateway to protect your network.
Changing the Default Password
For security reasons, the gateway has its own user name and password. After a period of inactivity
for a set length of time, the administrator login automatically disconnects. When prompted, enter
admin for the gateway user name and password for the gateway password. You can change the
password and the amount of time for the administrator login timeout.
Note: The user name and password are not the same as any user name or password your
may use to log in to your Internet connection.
NETGEAR recommends that you change this password to a more secure password. The ideal
password should contain no dictionary words from any language, and should be a mixture of both
upper and lower case letters, numbers, and symbols. Your password can be up to 30 characters.
To change the default password:
default user name of admin, default password of password, or using whatever password and
LAN address you have chosen for the gateway.

3. To change the password, first enter the old password, and then enter the new password twice.
4. Click Apply to save your changes.
Note: After changing the password, you will be required to log in again to continue
the configuration. If you have backed up the gateway settings previously, you
should do a new backup so that the saved settings file includes the new
password.
Blocking Keywords, Sites and Services
The gateway provides a variety of options for blocking Internet content and communications to the
gateway. You can control access to Internet content by screening for keywords within Web
addresses; you also can block access to all sites except those that are explicitly allowed. Blocking
options include:
•
•
•
Blocking access from your LAN to Internet locations that contain keywords that your specify.
Allowing access to only Web sites (domains) that you specify as allowed.
You can also block access to the Internet by a specific computer based on the hardware MAC
address of that computer. Blocking access to the Internet based on the hardware MAC address of
the computer or wireless adapter is described in “Using MAC Filtering to Block Access” on
page 3-4.
To configure any of the parental controls, you must be logged in as a parent.

Inbound and Outbound Rules
You can use firewall rules to block or allow specific traffic passing through from one side to the
other. Inbound rules (WAN to LAN) restrict access by outsiders to private resources, selectively
determine what outside resources local users can have access to.
A firewall has two default rules, one for inbound traffic and one for outbound. The default rules of
the gateway are:
•
Inbound: Block all access from outside except responses to requests from the LAN side.
Instructions for setting up inbound rules can be found in “Port Forwarding” on page 3-8
•
Outbound: Allow all access from the LAN side to the outside. Use Port Blocking to set up
outbound rules (see “Port Blocking” on page 3-7).
You may define more rules that specify exceptions to the default rules. By adding custom rules,
you can block or allow access based on the service or application, source or destination IP
addresses, and time of day.

Port Forwarding
You can use port forwarding to set up a rule that directs inbound traffic for a particular service to a
local server (for example, a Web server or game server) based on the destination port. This makes
the server visible and available to the Internet.
Unless you set up port forwarding, the gateway prevents this type of traffic.The gateway uses
Network Address Translation (NAT). NAT presents a single IP address for your network to the
Internet. Outside users cannot directly address your local computers.
Note: Some residential broadband ISP accounts do not allow you to run any server
processes (such as a Web or FTP server) from your location. Your ISP may check
for servers and may suspend your account if it discovers active services at your
location. If you are unsure, refer to the acceptable use policy of your ISP.
Before setting up Port Forwarding, consider the following:
•
If the IP address of the local server PC is assigned by DHCP, it may change when the PC is
rebooted. To avoid this, you can assign a static IP address to your server outside the range that
is assigned by DHCP, but in the same subnet as the rest of your LAN. By default, the IP
addresses in the range of 192.168.0.2 through 192.168.0.9 are reserved for this.
•
Local computers must access the local server using the local LAN address of the computer
(192.168.0.XXX, by default). Attempts by local computers to access the server using the
external WAN IP address will fail.
Remember that allowing inbound services opens holes in your firewall. Only enable those ports
that are necessary for your network.

Port Triggering
Port Triggering is an advanced feature that allows you to dynamically open inbound ports based on
outbound traffic on different ports. This feature can be used for gaming and other Internet
applications.
Note: Port Forwarding is similar to port triggering, but it is static and has some
limitations. Ports are open to traffic from the Internet until the port forwarding rule
is removed. Additionally, port forwarding does not work well for some
applications when your WAN IP address is assigned by DHCP, and is changed
frequently. Port Triggering opens an incoming port temporarily and does not
require the server on the internet to track your IP address if it is changed.
Port Triggering monitors outbound traffic. When the gateway detects traffic on the specified
outbound port, it remembers the IP address of the computer that sent the data and “triggers” the
incoming port. Incoming traffic on the triggered port is then forwarded to the triggering computer.
For example, port triggering can be used for Internet Relay Chat (IRC). When you connect to an
IRC server, the server tries to connect back on the port to do an Ident lookup. Unless you have
configured Port Forwarding to open that port, the traffic will be blocked. In this example, the
initial login to the server in the range of ports is detected. This triggers the gateway to temporarily
forward the port to the PC that initiated the login.
To configure Port Triggering
1. Under Advanced on the main menu, select Port Triggering The Port Triggering screen will
display.
2. In the Trigger Range, enter the outbound ports that will be monitored for activity. This will be
the “trigger.”
3. In the Target Range, enter the inbound ports that should be forwarded when the trigger occurs.
4. Select the appropriate protocol: TCP, UDP or Both.
5. Check the Enable box

1. Either remove the check from the Enable box to temporarily disable the rule, or
2. Select the rule and click Delete.
Setting Up A Default DMZ Host
The Default DMZ Server feature is helpful when using some online games and video conferencing
applications that are incompatible with NAT. The gateway is programmed to recognize some of
these applications and to work properly with them, but there are other applications that may not
function well. In some cases, one local PC can run the application properly if that PC’s IP address
is entered as the Default DMZ Host.
Note: For security, you should avoid using the Default DMZ Server feature. When a
computer is designated as the Default DMZ Server, it loses much of the protection
of the firewall, and is exposed to many exploits from the Internet. If compromised,
the computer can be used to attack your network.

Incoming traffic from the Internet is normally discarded by the gateway unless the traffic is a
response to one of your local computers or a service that you have configured in the Port
Forwarding or Port Triggering page. Instead of discarding this traffic, you can have it forwarded to
one computer on your network. This computer is called the Default DMZ Host.
To assign a computer or server to be a DMZ Host:
1. From the Advanced menu, select DMZ Host.
Figure 3-8
2. Enter the IP address of the computer you would like to assign as a DMZ Host.
3. Click Apply.
To disable the DMZ Host, enter “0” and click Apply.
If you want the gateway to respond to a “ping” from the Internet, check the “Respond to Ping on
WAN Port” check box. This should only be used as a diagnostic tool, since it allows your gateway
to be discovered. Do not check this box unless you have a specific reason to do so.
Turning On Universal Plug and Play (UPnP)
Universal Plug and Play (UPnP) helps devices, such as Internet appliances and computers, access
the network and connect to other devices as needed. UPnP devices can automatically discover the
services from other registered UPnP devices on the network.
UPnP can be enabled or disabled for automatic device configuration. The default setting for UPnP
is disabled. If disabled, the router will not allow any device to automatically control the resources,
such as port forwarding (mapping), of the router.
Other features of UPnP:

•
Advertisement Period. The number entered in this field (in minutes) determines how often
the router will advertise (broadcast) its UPnP information. This value can range from 1 to 1440
minutes. The default period is for 30 minutes.
–
Shorter durations will ensure that control points have current device status at the expense
of additional network traffic.
–
Longer durations may compromise the freshness of the device status but can significantly
reduce network traffic.
•
•
Advertisement Time To Live. The time to live for the advertisement is measured in hops
(steps) for each UPnP packet sent. A hop is the number of steps allowed to propagate for each
UPnP advertisement before it disappears. The number of hops can range from 1 to 255. The
default value for the advertisement time to live is 4 hops, which should be fine for most home
networks. If you notice that some devices are not being updated or reached correctly, then you
may need to increase this value a little.
UPnP Portmap Table. The UPnP Portmap Table displays the IP address of each UPnP device
that is currently accessing the router and which ports (internal and external) that device has
opened. The UPnP Portmap Table also displays what type of port is opened and if that port is
still active for each IP address.

About LAN IP Settings
The gateway is preconfigured to use private IP addresses on the LAN side, and to act as a DHCP
server. The LAN IP settings are explained below:
•
LAN IP address: This is the IP address of the gateway. The default is 192.168.0.1.
Note: If you change the LAN IP address of the gateway while connected through the
browser, you will be disconnected. You must then open a new connection to
the new IP address and log in again
•
Subnet mask: This is the LAN subnet mask of the gateway. The default is 255.255.255.0.
Combined with the IP address, the subnet mask allows a device to know which other addresses
are local to it, and which must be reached through a gateway or router.
These addresses are part of the IETF-designated private address range for use in private
networks, and should be suitable in most applications. If your network has a requirement to
use a different IP addressing scheme, you can make those changes in the LAN IP page.

Using the Gateway as a DHCP Server
By default, the gateway is a DHCP server. It can assign IP, DNS server, and default gateway
addresses to all computers connected to the LAN. The default wireless voice gateway address is its
LAN address. The wireless voice gateway assigns IP addresses to the network computers from a
pool of addresses specified in the Starting Address and Ending Address fields. Each pool address
Note: If another device on your network is the DHCP server, or if you will manually
configure the network settings of all of your computers, select No for the DHCP
Server. For more information about DHCP and IP addresses, see the link to
“Preparing a Computer for Network Access:” in Appendix B.
The gateway delivers the following parameters to any LAN device that requests DHCP:
•
•
•
•
An IP Address from the range you have defined.
Subnet Mask.
Gateway IP Address is the gateway’s LAN IP address.
Primary DNS Server, if you entered a Primary DNS address in the Basic Settings page;
otherwise, the gateway’s LAN IP address.
•
Secondary DNS Server, if you entered a Secondary DNS address in the Basic Settings page.
Note: The gateway implements a DNS Relay function. When it receives a DNS request
on the LAN, it passes it to the DNS server specified on the WAN. It then relays the
response back to the original requesting PC.
Configuring the LAN IP Settings
You can use the LAN IP Setup page to configure LAN IP services such as the IP address of the
gateway and DHCP.
To configure the LAN IP:
1. Under Advance on the main menu, select LAN IP. The LAN IP screen will display.
