Hi
I am using fedora 11 on my system and it is having 2 NIC's, eth0 and eth1. I have internet connection connected to eth0 and i want to share internet to other PC whose NIC is connected to eth1.

How can i route this? Please help me with the routing table code.

turn on forwarding (echo 1 > /proc/sys/net/ipv4/ip_forward) usually can be done permanently in sysctl.conf

add a masquerade rule, something like iptables -t nat -A POSTROUTING -o eth0 -s 192.168.0.0/24 -j MASQUERADE

then put a route rule on the other PCs to send internet traffic that pc, typically a default route, like route add default gw ip.of.gateway.pc
