I am looking for a way to have multiple (2 in this case) WAN connections (Cable modems, again in my case) on a Linux box.
Two interfaces that connect to totally separate networks, not a problem; just configure the interfaces normally and you're done. Two interfaces that connect to the same place (the internet), well that's a little different.
http://lartc.org/ is the documentation you want to read. Chapter 4, specifically, but you will find reading the whole thing to be a mind-expanding experience.
