I've looked online and can't seem to find a HOW-TO on this. I've configured iptables to do a many to many NAT, but traffic is not accepted because the IP address does not exist on the outside interface. iptables -t nat -A POSTROUTING -s 192.168.1.0/24 -j SNAT --to 1.2.3.0/25 I'm thinking that I need to add a route for this to work, but I'm not terribly sure. Would something like this work? route add -net 1.2.3.0/25 gw 192.168.1.1 Or route add -net 1.2.3.0/25 gw 1.2.2.1 Or route add -net 1.2.3.0/25 dev eth0 Where eth0 is the external interface. Thanks, Robert
