linux firewall box w/2 nic's.... how to?

[codejammer007]

ok,,, i'm setting up a linux box for a friend... out of an older computer he never used anymore.....
i put redhat 9.0 on it.....
i got the dhcpd working on the internal network.... but i can't seem to get it to bridge the connections so i can get out to the internet....
it's a gateway 1.0 ghz, 512 mb ram computer..... w/ a 14 gb hd....

i tryed a bunch of stuff off of google.... but nothing worked......
i probily need to re-do all the iptables configs. and start from scratch....

i can get out to the internet with the linux box... but nothing else....
i haven't ever done to much with linux...

i need step by step instructions.......
any help is greatly appreachiated...
thanks alot,
bobby

Why don't you run a router / firewall operating system on it such as Smoothwall or IPCOP.

i've worked with redhat more than anyother linux...
so i just put that on there...
no really particular reason, other than some experence with it...

Resource Wise, you should probably install one of the dedicated OS's, as Chris mentioned.

i never messed with any of those....

dose it have a web browser?
do they have x?

Their both web page setup based, similar to any router you find in a store. They both have SSH as well though.

just a quick warning about smoothwall its a pain in the a** to get to work on older pc's and it doesn't like true static ip address from your ISP I learned that the hard way.

I haven't noticed it being hard to run on hardware, some motherboards it may just refuse to run on however. And I h ave not once heard of any issues with static IP's

if you want a good router software go with http://www.smoothwall.org its a pain in the butt to setup but after you know how get it working it works fine because on my setup I got 4 nics on it Red+Green+Orange+Purple
Red=Is your incoming and outgoing (ISP line)
Green=is your DHCP or your other computers hook up
Orange=Webserver
Purple= For Wireless Router
