Linux - ipautofw Q

[netsurfer]

I have a router running ShareTheNet (www.sharethenet.com), but it basically is a linux router/firewall that runs off a bootdisk.

There is a section to add manual startup commands, and here is where you can enter in linux commands... I think.

Anyway, I have this line (from STN's website):

ipautofw -A -r tcp 21001 21012 -h 192.168.0.10

192.168.0.10 is the IP of my machine, (the router is set to be 192.168.0.1), and 21001-21012 are tcp ports allocated for ICQ, and the connection preferences and everything have been set properly...

My biggest gripe is this, I rarely can stay connected for more than say... 10-15 minutes. And I'm pretty sure I know why. All I want to know is, is there any linux command that I can enter into my STN router to increase the timeout delay? the way it's set, the timeout is within... 60 seconds. If I don't touch ICQ (like send a msg, etc) the timeout will disappear, and I'll lose connection to the server... if I click Online again, it'll reestablish my connection, sometimes... other times, it'll get stucking in that "Connecting" loop and never really establish a connection...

---Edit---

UDP xxxxxxxx.xxxx:1391 fes-d016.icq.aol.com:4000 58

that line shows up in my router's socket connections. So I guess I need to know a linux command that I can add to extend the timeout period for that particular UDP packet.

Not familiar with that product, but if it's Linux based (based on kernel 2.0 if it uses IPAUTOFW), then this should do the trick.

http://www.linuxdoc.org/HOWTO/IP-Masquerade-HOWTO.html

You should probably look into using the newer tools like IPPORFW & IPMASQADM from the 2.2 kernel series though. I found them to me much easier to deal with.

I found a command:

ipfwadm -M -s 7200 10 160

Is there any place I can look to get help on all the syntax (like -M and -s)? From the page I found (http://www.linuxdoc.org/HOWTO/IP-Masquerade-HOWTO-3.html), it also modifies TCP timeouts, timeout for traffic after the TCP/IP "FIN" packet is received, and UDP timeouts.

All i'm interested in adjusting is the UDP timeout... is that possible?

--edit--

Btw, since this bootdisk (which runs linux 2.0.36) is made on a windows machine, I can't exactly delve into upgrading kernels. you can download the program and see how it works... fairly interesting, but it doesn't exactly let you get into linux.. (aside from a little box that lets you add extra commands).. which is good for me, since I've given up doing straight linux to a hard drive, and doing the whole router bit... for now.

coyote linux (http://www.vortech.net/coyote/coyote.htm) is similar to STN, and it uses the newer 2.2.x kernel which supports IPChains, but if I can stick with using STN... then i'd prefer to do so.
