The only guide I know of is http://www.netfilter.org/documentation/HOWTO/ NAT-HOWTO.html It should be fairly straight forward to set up though. Try the following: If you are using dhcp to get your ip address for your internet connection on eth0 and eth1 is your "local network" connection, you can set up dhcpd to give out ip addresses in the 192.168.1.0/24 range and use the following to enable natting: iptables -t nat -A POSTROUTING -o eth0 -s 192.168.1.0/24 -j MASQUERADE echo 1 > /proc/sys/net/ipv4/ip_forward If you have a static ip address for the internet that is 1.2.3.4 for example, the following should work: iptables -t nat -A POSTROUTING -o eth0 -s 192.168.1.0/24 -j SNAT --to-source 1.2.3.4 echo 1 > /proc/sys/net/ipv4/ip_forward If the above doesn't work, indicate how you have it set up so far and we can go from there.
