Using Linux for ICS

I'm not sure if this should go here or in INaS, but it is more Linux related. I need to setup something similar to ICS, except the computer sharing the connection will be running Linux. I have ICS on Windows 98 doing this right now, but want to switch it. I know you use iptables and NAT, but I am clueless how to do this.
I can't use Smoothwall because of my network card. It is wireless and only supported by ndiswrapper, and Smoothwall does not come with a module for it, and I would also like to run a web server on the computer. I looked at Clark Connect, but it doesn't include gcc, so I can't compile ndiswrapper. I have tried the ICS provided by Mandrake, but I can't get it to work (and would prefer to use something not rpm based).
Does anybody know of a distro that can do this for me, or of a tutorial or something of how to do this in a regular distro, such as Arch?
Thanks

Might help.

Okay, thanks. I didn't think about looking there. It says it is for a 2.4.x kernel, is it basically the same for the 2.6.x kernels?
Thanks

I *think* so but not sure.

Alright I'll reinstall some version sometime. Thanks.

Yes it's the same for kernel 2.4 and kernel 2.6. Most distros nowadays have a package for it.
In Debian I do "apt-get install ipmasq dnsmasq" that's all. If I want to enable DHCP I need to edit a single config file. The NAT and caching DNS work out of the box.

I have another question. Is there a way that I can track the bandwidth that I am using, similar to the bandwidth bar mod for Smoothwall?

there are various ways: ipac-ng, the outpuf of /sbin/ifconfig, the syslog entry pppd gives out when it stops, etc.

I can't get iptables to work. I tried it in Arch Linux, my other computer got an IP address just fine, but couldn't surf the web. I tried it in Overclockix 3.7, I couldn't get the dhcp server to run because I couldn't change the config since it was being run on the cd. I tried it in Knoppix 3.8.1, dhcp worked fine, but I couldn't browse the web. I did everything it says to in that guide in the sticky, except replacing the addresses with mine. Am I doing something wrong, or is there something I need to do after that?
Thanks

Bump, I still can't get it to work. I think I might be needing to set something else up or change the config somehow. I tried setting it up in Windows Server 2003 EE with routes and a dhcp server, but it didn't work. I could get dhcp, but I still couldn't browse the web or ping sites. Is there something else that ICS in Windows 98 includes that I am not setting up?
