I have installed suse 9.2 on my computer. I connect to the internect thru a built in lan card and a cable modem. I have no problem connecting to the internet but I can`t seem to enable internet connection sharing. I have two other computers connected to a hub which are connected to my linux computer thru a 2nd ethernet card that is plugged into a pci slot on the linux computer. The computers that are connected to the hub are running windows xp pro. How do i enable internet connection sharing on the linux computer. I`m sure the ethernet cards are configured properly because I`m able to ping the other computers, just can`t figure out how to enable internet connection sharing on the linux computer.

Check out the IP Masquerading HOWTO which will explain what you want to do. Basically, write the iptables rules to do NAT andthe echo 1 > /proc/sys/net/ipv4/ip_forward to enable packet forwarding, but read the guide for more details.

just enable suse firewall in yast and select ip masquerading then it will act as a router for your other computers

Tried this and it didn`t work. I don't know why they don't make it easy like they do in mandriva.

I just managed to share my internet connection using suse 9.2 with my other PC running windows XP.
Just follow the instructions in the above link, it is pretty straightfoward.
From what I can follow in this thread, you probably just need one more step, which is getting the DHCP server to run on your suse 9.2
