I would look at some guides for how to set up iptables, as it will basically allow you to route packets between interfaces according to rules you set up. iptables is much more than just a firewall interface and you can pretty much give it a massive list of rules to route data through networks. That tiny router that almost everyone uses to connect to the internet with? That thing is running Linux with iptables fully set up. Amongst others, look at this howtoforge guide and this epic guide at pettingers The main one I can find is this one which claims to be A basic firewall configuration suitable for a gateway/nat and supports eth0 for the external interface and eth1 for the internal interface. Ubuntu has an IpTables Howto and as an example has a program called UFW (Uncomplicated FireWall) that may be able to configure iptables for you, it also has a gui frontend called gufw which may be of use. | |||
