Hey I was wondering how I would go about writing NAT software. I don't really have any clue where to start since I usually code game based stuff (OGL, DX, etc) and it's been over 4 years since I even touched winsock.

Explaining my situation might help:

I'm stuck with AOL Cable(through Road Runner) and I wanted to have one connection run AOL and share the internet with the other PC's without them "signing on"

I've already tried alot of bloated NAT software so I just decided to code something myself, any resources would be helpful.
