First enable routing on your linux box:
"echo 1 > /proc/sys/net/ipv4/ip_forward"

Then enable masquerading of the packets that go out to the public network (lets presume that its eth0 that its conencted to internet):
"iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE"

This should be enough. Hope it helps

In RedHat (and Mandrake), if you want to set up Internet Connection Sharing (also known as IP Forwarding and Masquerading), take a look at this thread.

If you have some difficulties and want to debug, these threads have some debugging techniques.
