Chapter 1: Introduction
The SOHOware BroadGuard Secure cable/DSL Router provides convenient
Internet access to office/family users by sharing a single Broadband Service
Provider (BSP) account. The BroadGuard functions with cable/DSL modems and
allows up to 253 computers to share secure broadband Internet access
simultaneously.
Figure 1. BroadGuard Connections
Embedded Network Address Translation (NAT) enables you to use a private set of
IP addresses that the BroadGuard translates into a single public IP address.
The BroadGuard can also act as a DHCP server by automatically allocating a
dynamic IP address to each computer on the network.
An enhanced firewall and the Access Control feature monitor incoming data
packets and filter server requests. Together they allow parents/employers to see
how the network connection is being used, and protect all PCs behind the
BroadGuard.

Chapter 2: Installation
What You Need
Before installing the SOHOware BroadGuard you need the following:
Any Network Operating System with:
•
•
•
TCP/IP installed
Internet browser installed
10Mbps/100Mbps or 10/100Mbps Ethernet network adapters installed
Broadband Internet Account
You should be subscribed to a broadband Internet service and have a cable/DSL
modem with a 10Base-T interface. Know whether your Public IP address is fixed
or is dynamically assigned (ask your Broadband Service Provider).
1. If your IP address is dynamically assigned (most common), the BroadGuard
will automatically get a public IP address from your ISP through the modem.
You will not need to do any IP address configuration.
There is no need to enter any information in Broadband Connection unless
your BSP has assigned you specific Internet connection information (Host
Name, Domain Name, MAC address authentication, PPPoE, or a static IP
address).
To do a manual setup, type 192.168.1.1 into the web address location on a
web browser on any connected PC. Enter the factory default user name
admin and password 1234. After clicking OK you will enter the setup home
page. Click the Broadband Connection link to begin setup of the broadband
connection.
2. If you have an AT&T (formerly MediaOne) cable service, or any service that
requires a Media Access Control (MAC) address for authentication, when you
are setting up the BroadGuard for first use, only the PC with the registered
Ethernet card’s MAC address can be connected to the BroadGuard.
3. If you have a DSL service with PPPoE, obtain the following information from
your BSP:
•
•
•
The user login name
The login password
Service name (some BSPs may not require you to use this)
SOHOware® Secure Cable/DSL Router 5

4. If you have a fixed public IP address, obtain the following information from
your ISP
•
•
•
The assigned Gateway IP address
Domain Name Server’s IP address
Subnet Mask
Making a Connection
All the connection ports are on the rear panel of the BroadGuard. Follow the steps
below to complete the hardware installation.
step1.
Connect to a cable/DSL modem - Two cables are supplied with the
SOHOware NBG800. The white cable (straight-through) is for
connecting a cable modem to the Cable/DSL port; the green one
(cross-over) is for connecting a DSL modem to the cable/DSL port.
Plug one end of the cable into the cable/DSL port of the BroadGuard
and the other end into the Ethernet port of the cable/DSL modem. If
the cable is connected correctly, the Cable/DSL LED will remain lit
(the cable/DSL modem must be turned on). If not, try switching the
cables, green for white
step2.
step3.
Connect to the PCs - Use a standard RJ-45 Ethernet cable (not
provided) to connect the Ethernet LAN adapters in the computers to
the BroadGuard LAN ports
Install the power adapter - Plug the power adapter into an AC power
outlet. Plug the other end into the BroadGuard. The Power LED
should light immediately
Note: Use only the power adapter supplied with the BroadGuard
Figure 4. Connecting the BroadGuard
Note: Only one PC should be connected to the BroadGuard during setting up

Some BSPs use an Ethernet adapter’s MAC address as an identifier to provide
Internet service. In these cases you need to clone the Ethernet adapters MAC
address to the BroadGuard. At the BroadGuard, disconnect the Ethernet cables
from the other PCs on the network, leaving only the PC with the Ethernet adapter
that you wish to register connected.
Note: If you previously used a registered MAC address to connect to your
broadband service, you need to clone this Ethernet adapter’s MAC address to the
BroadGuard.
Network Extension
If you want to connect more users to your network, or use a wireless connection
through the BroadGuard, refer to the following section:
Wired LAN Extension
This section describes how to extend your BroadGuard LAN using one of our
SOHOware Home series products, e.g. a 10Mbps or 10/100Mbps Ethernet

MAC Address Clone: Some BSPs use an Ethernet adapter’s MAC address as an
identifier to provide Internet service. In these cases, you need to clone the Ethernet
adapter’s MAC address to the BroadGuard. At the BroadGuard, disconnect the
Ethernet cables from the other PCs on the network, leaving only the PC with the
Ethernet adapter that you wish to register connected.
Note: If you previously used a registered MAC address to connect to your
broadband service, you need to use the same Ethernet adapter and clone its MAC
address to the BroadGuard.
There are two MAC addresses shown on the screen. One is the PC’s Ethernet
card’s (this PC is connected to the BroadGuard via Ethernet), the other is the
BroadGuard’s. Click Clone MAC to change the IP address of the BroadGuard to
that of the Ethernet card. Click Restore MAC to restore the original MAC address
of the BroadGuard.
Note: After saving the settings and restarting the BroadGuard, you MUST turn

Hacker Attack E-mail Alerts
Figure 38. Hacker Attack E-mail Alerts
An anti-attack algorithm is built in to the BroadGuard so that it can protect client
PCs from conventional attacks. With BroadGuard, you have a professional
firewall but without any specialized setup/configuration. BroadGuard gives your
network the capability to prevent many kinds of hackers’ attacks.
If you turn on the e-mail alert function, whenever BroadGuard detects an Internet
attack it will automatically send an e-mail with an attached log file to you.
The info. will look something like the following:
udp -(203.69.97.139 ,211.55.79.155 )-840 -port scan attack-forward
udp -(203.69.97.139 ,211.55.79.155 )-546 -port scan attack-forward
udp -(203.69.97.139 ,211.55.79.155 )-544 -port scan attack-forward
In the example above, the first IP address (203.69.97.139) on each line indicates
the address the hacker is using. The second (211.55.79.155) is the user's Internet
IP address. As for ports 840, 546, and 544, they are the numbers of ports that are
being attacked.
Forward this e-mail to your BSP for analysis.
Note: The e-mail alert is sent at approximately the same time your computer is
attacked.
Enter the e-mail address that the warnings should be sent to.
The e-mail server address can be obtained from your broadband service provider.
Click Save to store the settings. Click Restart to initialize the BroadGuard with the

DMZ Host
Figure 42. DMZ Host
Usually all PCs connected to the BroadGuard are protected from Internet intruders
by a built-in firewall. For some kinds of Internet applications, for example,
Internet interactive games, video-conferencing, VPN (Virtual Private Networks), or
as an e-mail server etc., computers must be exposed to the Internet. The DMZ
Host function assigns one of the client computers to be exposed.
BroadGuard setting: You must assign a static IP address to the Client PC to be
exposed to the Internet, then click Save to make the setting effective. Click Restart
to initialize the BroadGuard with the updated settings.
Once the static IP address is assigned to a specific client PC, you MUST specify
the PC as the DMZ Host.
DMZ Host Disable
For extra security, when you do not require the DMZ Host to be exposed to the
Internet, you should disable this function by entering a 0 (zero) in the Client PC (IP
Address) box.
Note: The DMZ PC operates outside the protection of the BroadGuard’s built-in
firewall. If the DMZ PC is not operating in the DMZ role, but is still powered-on
for local use, you should disable DMZ Host to prevent hackers from accessing the
PC.

DHCP Settings
Figure 43. DHCP Settings
Under normal operation, all client PCs’ IP addresses are automatically assigned by
the BroadGuard’s DHCP server.
The IP address range runs from 192.168.1.1 to 192.168.1.254. Up to 253 IP
addresses may be assigned to client PCs. The IP address 192.168.1.1 is reserved
for the BroadGuard. The other IP addresses are divided into two IP groups. One is
the dynamic IP group, the other is the static IP group.
The dynamic IP start address may be specified by the user, e.g. 192.168.1.100
(default value). Once this start IP address has been assigned by you, all IP
addresses running from 192.168.1.100 to 192.168.1.254 will be part of the dynamic
IP address pool. IP addresses from 192.168.1.2 to 192.168.1.99 will be available
as static IP addresses.

Chapter 4: Troubleshooting
If you cannot find your problem listed below, see Chapter 5: FAQs, page 49, or
see the BroadGuard FAQ at the SOHOware website.
1. I can’t connect to the BroadGuard. The BroadGuard is properly installed,
LAN connections are OK, and it is powered ON.
ꢀ
ꢀ
ꢀ
Ensure that your PC and the BroadGuard are on the same network segment.
If you are not sure, restart the BroadGuard, let the PC get the IP address
automatically.
Ensure that your PC is using a static IP Address within the default range of
192.168.1.2 to 192.168.1.254 and is thus compatible with the BroadGuard
default IP Address of 192.168.1.1.
The Subnet Mask should be set to 255.255.255.0 to match the BroadGuard.
On the client PC, you can check these settings by using Control
Panel/Network to check the properties for the TCP/IP protocols.
2. The Status LED stays lit when it shouldn’t.
The Status LED lights when the device is powered up and checks for proper
operation. After finishing the checking procedure, the LED turns off to show the
system is working fine.
If the LED remains lit after this time, the BroadGuard is not working properly.
Contact your dealer.
3. I can’t browse through the BroadGuard.
ꢀ
Check that both ends of the network cable and power adapter are properly
connected. Check that all LEDs on the front panel are functioning properly.
Use Status (Figure 55) to check that your BroadGuard is still connected to
your BSP. If there is no public IP address shown on the screen, the problem
lies with the BSP.

information will be cleared, even though your computer may still be switched on.
To prevent this problem:
step1.
step2.
step3.
Shut down your PC
Power your BroadGuard on
Turn your PCs on
6. I can connect to the BroadGuard, but can't get outside connections
ꢀ
Ensure that all of your cabling is properly connected and that all of the
BroadGuard’s cable/DSL and LAN LEDs are correctly illuminated.
ꢀ
Power down your cable/DSL modem and BroadGuard for a few seconds.
Then turn the cable/DSL modem on. After the modem goes through its self-
test, turn the BroadGuard on. After the BroadGuard goes through its self-test,
check whether you can get an outside connection.
ꢀ
ꢀ
ꢀ
Ensure that your cable or DSL modem is DHCP-capable.
Make sure all broadband connection setup is correct.
The problem may be caused by your BSP (Broadband Service Provider)
issuing a different IP address from time to time. The BroadGuard gets its
public IP from the BSP’s DHCP server automatically. The BroadGuard must
renew the public IP if the BSP cancels the originally assigned IP address.

Chapter 5: FAQs
ꢀ
How many PCs simultaneously accessing the Internet can be supported
by the BroadGuard?
253 PCs may simultaneously access the Internet via the BroadGuard.
ꢀ
Where should we install the BroadGuard on our network?
In a typical environment, the BroadGuard is installed between a cable/DSL
modem and LAN. Connect the BroadGuard to the cable/DSL modem with
Cat.5 RJ-45 cable.
Plug one end of the cable into the WAN port of the BroadGuard and the other
end into the Ethernet port of the cable/DSL modem.
ꢀ
Does the BroadGuard support IPX or AppleTalk?
No. TCP/IP is the protocol standard for the Internet and has become the
global standard for communications. IPX, a NetWare communications
protocol used only to route messages from one node to another, and
AppleTalk, a communications protocol used on Apple and Macintosh
networks, can be used for LAN to LAN connections, but those protocols
cannot connect from WAN to LAN.
ꢀ
ꢀ
ꢀ
I’m using Linux. Does the BroadGuard support this operating system?
Yes. The BroadGuard is compatible with any operating system.
Does the BroadGuard support 100Mbps Fast Ethernet?
Yes. Both 10 and 100Mbps Fast Ethernet are supported.
Does the BroadGuard support ICQ send file?
Yes, with the following fix: ICQ menu-> preference -> connections tab->
check "I am behind a firewall or proxy", and set the firewall time-out to 80
seconds. An Internet user can then send a file to a user behind the
BroadGuard.
ꢀ
ꢀ
How do I get Napster to work with the BroadGuard?
Napster is fully compatible with the BroadGuard and requires no special
settings.
Can multiple gamers on the LAN get on one game server and play
simultaneously with just one public IP address?
It depends on which network game or what kind of game server you are using.
For example, Unreal Tournament supports multi-login with one public IP.
ꢀ
ꢀ
How can I avoid receiving corrupted FTP downloads?
If you are experiencing corrupted files when you download a file with your
FTP client, try using another FTP program.
How will I be notified of new BroadGuard firmware upgrades?
All firmware upgrades are posted on the SOHOware website at
SOHOware® Secure Cable/DSL Router 49
Download from Www.Somanuals.com. All Manuals Search And Download.
ꢀ
ꢀ
ꢀ
Does the BroadGuard pass PPTP packets?
Yes.
Does the BroadGuard support IPSec?
This function will be supported in later firmware upgrades.
What is the recommended maximum number of VPN sessions I can run
on the BroadGuard?
We recommend the number of sessions is five or less to prevent influencing
the throughput of the BroadGuard.
ꢀ
ꢀ
ꢀ
Will the BroadGuard function in a Macintosh environment?
Yes, but the BroadGuard’s setup pages are accessible only through Internet
Explorer v4.0 or Netscape Navigator v4.0 or higher for Macintosh.
With which type of firewall is the BroadGuard equipped?
The BroadGuard uses NAT, anti-DoS (Denial of Service) and (SPI) Stateful
Packet Inspection.
What is DoS (Denial of Service)?
The goal of a Denial of Service (DoS) attack is not to steal information, but to
disable a device or network so users no longer have access to network
resources. For example, "TearDrop", a DoS hacker tool which is widely
available on the Internet, allows users to remotely crash any unprotected
Windows computer on the Internet. Most types of Internet attacks try to
exploit the weaknesses in the TCP stacks of the operating systems of host
machines. BroadGuard protects against the following types of DoS attacks:
ꢀ
ꢀ
ꢀ
ꢀ
ꢀ
ꢀ
ꢀ
SYN Flooding
Ping of Death
LAND attacks
Smurf attacks
IP Spoofing
TearDrop
WinNuke
ꢀ
What is Stateful Packet Inspection (SPI)?
Stateful Packet Inspection is a technology similar to that used in enterprise-
level firewall products. It is generally regarded as a "state of the art" firewall
technology. With SPI, the BroadGuard makes security decisions based on the
origination of Internet sessions. The BroadGuard will allow incoming data

from the Internet only if it is part of a session that was initiated by one of the
users on the secure Local Area Network (LAN), but will block all
communications that are initiated from the Internet. SPI has the added benefit
of being easy to manage, making it ideal for those who don't have MIS people
for networking maintenance.
ꢀ
ꢀ
Does the BroadGuard support routing protocols?
Yes, it support both RIP I & RIP II.
I am not able to get the web configuration screen for the BroadGuard.
What can I do?
You may have to remove the proxy settings on your Internet browser, e.g.,
Netscape Navigator or Internet Explorer. Or remove the dial-up settings on
your browser.
ꢀ
Will the BroadGuard allow me to use my own public IP and Domain?
The BroadGuard allows for customization of your public IP and Domain. If
you use a cable connection see Figure 35, page 28. For DSL users, see Figure
37, page 29.
ꢀ
ꢀ
Is there an internal cable or DSL modem in the BroadGuard?
No, the BroadGuard must work in conjunction with an external cable or DSL
modem.
Which modems are compatible with the BroadGuard?
The BroadGuard is compatible with virtually any cable or DSL modem that
supports Ethernet.
ꢀ
ꢀ
How can I check whether I have static DHCP IP Addresses?
Consult your BSP to confirm the information.
How do I get Half-Life: Team Fortress to Work with the BroadGuard?
If you want to host a game, you must expose your PC to the Internet using
DMZ Host (see DMZ Host, page 34). If you only want to join a game hosted
by somebody else, then there is no need to set your machine as a DMZ Host.
ꢀ
ꢀ
How do I get mIRC to work with the BroadGuard?
You must expose your PC to the Internet using DMZ Host (see DMZ Host,
page 34).
How can I learn more about Internet safety issues?
As parents, protecting children from accessing websites that contain improper
content is critical. Many sites discuss this issue on the Internet. You can use

your office VPN server from your home office and you also can build a VPN
server for mobile sales to access for urgent purposes. BroadGuard supports all
PPTP packet based VPN software
BroadGuard VPN Server Configuration
To run a VPN server, you will find using a static IP will greatly simplify your
system management (as the IP address never changes). The PC must be exposed to
the Internet as a DMZ Host. Only one PC can be used as a VPN server as only one
PC may be set as a DMZ Host.

Appendix B: GLOSSARY
Ethernet
One of the most common Local Area Network (LAN) protocols. Ethernet uses a
bus topology that supports a data transfer rate of 10Mbps.
Fast Ethernet
Much the same as Ethernet but 10 times faster; requires upgraded network cards
and hubs.
Protocol
A protocol is a set of rules for communicating between computers.
10Base-T
A variant of Ethernet that allows computers to be networked at 10Mbps via twisted
pair cable.
100Base-TX
A variant of Ethernet that allows computers to be networked at 100Mbps via
twisted pair cable.
Browser
A software application used to locate and display Web pages, such as Netscape
Navigator and Microsoft Internet Explorer.
DHCP (Dynamic Host Configuration Protocol)
DHCP is a protocol that assigns temporary IP addresses to PCs. Without DHCP
the IP address must be entered manually at each computer.
Domain Name
The Domain Name identifies one or more IP addresses. For example, the domain
name of sohoware.com represents about a dozen IP addresses.
URL (Uniform Resource Locator)
A Uniform Resource Locator is a standard for specifying the location of an object
on the Internet, such as a file or a newsgroup. URLs are used extensively on the
World Wide Web. They are used in HTML documents to specify the target of a
hyperlink, which is often another HTML document (possibly stored on another
computer).
DNS (Domain Name Server)
A server used to translate a Domain Name to a numerical form IP address.
PPPoE
68 SOHOware® Secure Cable/DSL Router
Download from Www.Somanuals.com. All Manuals Search And Download.
PPPoE supports reliable and straightforward end-user authentication with no
security risk and can provide a range of operational benefits to both the subscriber
as well as the service provider. Among these are network management and
diagnostic capabilities that can identify operational problems and automatically
offer resolutions.
Firewall
A security system used to enforce an access control policy between a LAN and the
Internet.
Gateway
A device that links two different networks.
Internet
A global network that connects millions of computers for information exchange.
IP Address
The Internet Protocol (IP) is a set of basic rules for network communication. Each
computer on the Internet has a unique IP address (e.g. 192.168.1.2) and its IP
functions as an I.D. number/identifier/address.
BSP (Broadband Service Provider)
A BSP is a company that provides individuals or companies broadband access to
the Internet and other related Internet services via cable or DSL.
Local Area Network (LAN)
A LAN is a network of interconnected workstations, sharing the resources of a
single server or each other, within a relatively small geographic area.
LAN Adapter
A device that connects the computer to the network cable.
MAC Address
Short for Media Access Control Address, a hardware address that uniquely
identifies each node on a network.
NAT (Network Address Translation)
A routing protocol that allows global IP addresses to be translated into multiple
private IP addresses for use on internal LAN networks. The explosion in the use of
the Internet has created a critical problem for the Internet Assigned Numbers
Authority (IANA) which is charged with assigning IP addresses to Internet users,
ISPs, etc. NAT is a technology that has been introduced to help maximize the
utilization of assigned IANA or global IP addresses.
TCP/IP
SOHOware® Secure Cable/DSL Router 69
Download from Www.Somanuals.com. All Manuals Search And Download.
TCP/IP protocols are used for Internet communications and consist of:
ꢀ
TCP (Transmission Control Protocol), which uses a set of rules to exchange
messages with other Internet points
ꢀ
IP (Internet Protocol), which uses a set of rules to identify Internet addresses
on the Internet. Every computer on the Internet has a unique IP address. The
IP protocol helps Internet users to identify each sender or receiver of
information that is sent across the Internet
VPN
Virtual Private Network: The use of encryption in the lower protocol layers to
provide a secure connection through an otherwise insecure network, typically the
Internet.
BBS (Bulletin Board Service)
A computer and associated software that typically provides an electronic message
database where people can log in and leave messages. Apart from public message
areas, a BBS may provide archives of files, personal electronic mail, and any other
services or activities of interest to the bulletin board's system operator (the
"sysop").
News Forum
An electronic meeting place where people can exchange news or discuss common
interests.
Hacker
A person who enjoys exploring the details of programmable systems and how to
stretch their capabilities, as opposed to most users, who prefer to learn only the
minimum necessary. Recently misused to describe a Cracker. See the next item.
Cracker
An individual who attempts to gain unauthorized access to a computer system.
These individuals are often malicious. Contrary to widespread myth, cracking does
not usually involve some mysterious leap of hackerly brilliance, but rather
persistence and the dogged repetition of a handful of fairly well-known tricks that
exploit common weaknesses in the security of target systems.
Firmware
Software stored in read-only memory (ROM) or programmable ROM (PROM).
Easier to change than hardware, but harder than software stored on disk. Firmware
is often responsible for the behavior of a system when it is first switched on.
