I want to forward traffic destined for a specific ip from my internal network via a specific interface. I have two interfaces which are currently load balanced. I need all requests for a certain ip to go out via eth0 otherwise my external ip changes and sessions are dropped.

eg. all requests from 10.1.1.1/24 to ip 11.22.33.44 on port 443 must go out via interface eth0.

How can I do this with iptables?
