Force service on certain interface

Hello there!

I have a dual internet routing linux computer. One nic has a static IP (eth2). Is there a way to setup iptables to use only eth2 for outgoing email?

Thank you

Do you have a valid path to the internet on more than one ethernet device? What software routes or divides the traffic?

As for your question, I think I would use the routing table. Maybe something like this:

Code:

route add -host $SMTP_SERVER dev eth2

Hi!, that looks good, but is there a way to route only SMTP traffic through eth2?

thank you :-)
