Frequently Asked Questions
Broadband Firewall Router with 4-Port Switch/VPN Endpoint
What is Network Address Translation and what is it used for?
Network Address Translation (NAT) translates multiple IP addresses on your local network to one public address
that is sent out to the Internet. This adds a level of security since the address of a PC connected to the network is
never transmitted on the Internet. Furthermore, NAT allows the Router to be used with low cost Internet
accounts, such as DSL or cable modems, when only one TCP/IP address is provided by the ISP. The user may
have many private addresses behind this single address provided by the ISP.
Does the Router support any operating system other than Windows 98, Windows 2000,or Windows XP?
Yes, but Linksys does not, at this time, provide technical support for setup, configuration or troubleshooting of
any non-Windows operating systems.
Does the Router support ICQ send file?
Yes, with the following fix: click ICQ menu -> preference -> connections tab->, and check I am behind a firewall
or proxy. Then set the firewall time-out to 80 seconds in the firewall setting. The Internet user can then send a file
to a user behind the Router.
I set up an Unreal Tournament Server, but others on the network cannot join. What do I need to do?
If you have a dedicated Unreal Tournament server running, you need to create a static IP for each of the
network’s computers and forward ports 7777, 7778, 7779, 7780, 7781, and 27900 to the IP address of the server.
You can also use a port forwarding range of 7777 ~ 27900. If you want to use the UT Server Admin, forward
another port (8080 usually works well but is used for remote admin. You may have to disable this.), and then in
the [UWeb.WebServer] section of the server.ini file, set the ListenPort to 8080 (to match the mapped port above)
and ServerName to the IP assigned to the Router from your ISP.
Can multiple gamers on the network 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 do I get Half-Life: Team Fortress to work with the Router?
The default client port for Half-Life is 27005. The computers on your network need to have “+clientport 2700x”
added to the HL shortcut command line; the x would be 6, 7, 8, and on up. This lets multiple computers connect
to the same server. One problem: Version 1.0.1.6 won’t let multiple computers with the same CD key connect at
the same time, even if on the same network (not a problem with 1.0.1.3). As far as hosting games, the HL server
does not need to be in the DMZ. Just forward port 27015 to the local IP address of the server computer.
