Someone wanted to see more posts in here, so:

Anyone got some good sources for redirections rules for running IP Masquerading and NAT routing? I've been meaning to replace my proxy server with a nice solid Linux solution, but it would be nice to have some info going into it. What I'm looking for are some good application rules for stuff like ICQ, and other programs. I can puzzle them out on my own, but I'd rather not have to ramp up that fast on install day. Any links or info would be handy.
