Post Three ethernet adapters. Two bridged. One WAN


If I have three ethernet adapters on my machine, all with different interfaces (example eth0 eth1 eth2) how would I create a configuration where the eth0 is the only adapter that provides actual internet access to the machine its self. I want eth1 as data input for a passive network and eth2 as the output from eth1; only allowing usable internet access on eth0.

Can we assume that eth0 is your public interface connected to your ISP and that eth1 and eth2 are private subnets?
If so I would imagine eth0 already has the default route for all internet traffic. You should just be able to polish up with IPTABLES
