How will I be notified of new router firmware upgrades? All Linksys firmware
upgrades are posted on the Linksys website at www.linksys.com, where they
can be downloaded for free. The router's firmware can be upgraded with
TFTP programs. If your Router’s Internet connection is working well, there is
no need to download a newer firmware version, unless that version contains
new features that you would like to use. Downloading a more current version
of Router firmware will not enhance the quality or speed of your Internet con-
nection, and may disrupt your current connection stability.
Will the router function in a Macintosh environment? Yes, but the router’s setup
pages are accessible only through Internet Explorer v4.0 or Netscape
Navigator v4.0 or higher for Macintosh.
I am not able to get the web configuration screen for the Router. 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. Check with your browser documentation, and make sure that
your browser is set to connect directly and that any dial-up is disabled. Make
sure that Internet Explorer is set to Never dial a connection by clicking on
Tools, Internet Options, Connection tab. For Netscape, click on Edit,
Preferences, Advanced, Proxy, and make sure that the setting is Direct con-
nection to the Internet.
What is DMZ Hosting? Demilitarized Zone (DMZ) allows one IP address (com-
puter) to be exposed to the Internet. Some applications require multiple
TCP/IP ports to be open. It is recommended that you set your computer with
a static IP if you want to use DMZ Hosting. To get the LAN IP address, see
“Appendix F: Finding the MAC Address and IP Address for Your Network
Adapter.”
If DMZ Hosting is used, does the exposed user share the public IP with the Router?
No.
Does the Router pass PPTP packets or actively route PPTP sessions? The router
allows PPTP packets to pass through.
Is the Router cross-platform compatible? Any platform that supports Ethernet
and TCP/IP is compatible with the Router.
How many ports can be simultaneously forwarded? Theoretically, the Router can
establish 520 sessions at the same time, but you can only forward 10 ranges
of ports.
I set up an Unreal Tournament Server, but others on the LAN 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 LAN 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 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 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 LAN 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 LAN (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.
How can I block corrupted FTP downloads? If you are experiencing corrupted files
when you download a file with your FTP client, try using another FTP program.
The web page hangs; downloads are corrupt, or nothing but junk characters are
being displayed on the screen. What do I need to do? Force your NIC to
10Mbps or half duplex mode, and turn off the “Auto-negotiate” feature of
your NIC as a temporary measure. (Please look at the Network Control Panel,
in your Ethernet Adapter’s Advanced Properties tab.) Make sure that your
proxy setting is disabled in the browser. Check our website at
www.linksys.com for more information.
If all else fails in the installation, what can I do? Reset the router by holding down
the reset button until the Diag LED fully turns on and off. Reset your cable
or DSL modem by powering the unit off and then on. Obtain and flash the
latest firmware release that is readily available on the Linksys website,
www.linksys.com.
