Hi,

I was wondering if anyone could advise me? I have a web server live on the internet, which has two internet live network cards, on different IP addresses.

Lets say, eth0 has the IP : 213.254.182.144/24 and eth1 has the IP : 193.128.89.158/24

Both are internet reachable.

I would like to define some routing rules such that any traffic that originated through eth0, is sent back out via eth0, and likewise, traffic that came through eth1 goes out via eth1.

I was thinking of something like :

route add default gw 213.254.182.145 eth0 and route add default gw 193.128.89.157 eth1

where 213.254.182.145 and 193.128.89.157 are both routers.

Would this work? I've not tried it yet and so this is all theory so far.

Your system should send replies automatically to the nearest known route back to the computer that sent the request, which in most cases will be router that passed on the request and the card that received the request, unless there is a route statement that overrides it. You can only have one "default" gateway, which is where packets go when there is no other known route. Routes are defined by destination, not be where the request came from. So, if you always want to reply to particular networks through a particular router, you can do that with route statements. You system will add to the routes you define dynamically based on other networks and hosts it learns about while it is running. Hope this helps.
