Routing certain ports to one Network Interface and all of the rest to another

T0PAZ · 12-17-2011, 04:06 PM

I have 3 Network Interfaces (eth0, usb0, and wlan0). I would like to make all connections going to certain destination ports (i.e.: 80, 443, etc.) go through either eth0, or wlan0. While making all of the rest of my traffic/ports go through usb0.

Currently it just defaults all of my traffic to eth0, unless I disable eth0, in which case it defaults it all to usb0.

You might find the following helpful. I know that what you want to do can be done, and I did have to do something similar for a Network Applications class but cannot remember all of the steps needed.

What you will want to make sure you have in your interface config files is that they are on at boot. You may find the following article useful as I referred to it while in class:

hope this helps get you pointed in the right direction
