Hello, I've got a question about routing under the 2.2.15 kernel. I have two connections to the internet, say 1.2.3.4 (gateway 1.2.3.1) and 20.20.20.20 (gateway 20.20.20.1). Currently, it seems I can only set one "default" gateway. So if traffic comes into 1.2.3.4, and my default gw is 20.20.20.1, all the return traffic goes out 20.20.20.1. The weird thing is that if I set my default gw to be 20.20.20.1, pings to 20.20.20.20 work fine, and pings to 1.2.3.4 work ok (the return goes through 20.20.20.1). However, if I have my gw set to 1.2.3.1, I can ping 1.2.3.4 ok, but not 20.20.20.20. I see the return ping from 20.20.20.20 going out to the 1.2.3.4 interface, but it never seems to get back. Could this be some sort of ISP configuration issue? In my case, the 1.2.3.4 line goes to a dsl router. Can Linux's routing be configured such that incoming traffic (http, mail, etc..) on 1.2.3.4 returns back thru 1.2.3.1, and traffic coming into 20.20.20.20 returns back thru its same interface (20.20.20.1)?
