But once connected, the gateway needs to be able to pass packets designated for the computer on the LAN that requested the connection, right? For that, I understood I'd need something like ipchains or iptables - to route packets to where they're supposed to go on my LAN. I didn't have any notion that ipchains would be involved in shutting down the connection to the ISP - sorry if I confused things there. I also may be butchering basic networking conceptions and terminology. I'm very new to the whole thing. Perhaps I'll decide eventually that it's just beyond me, or that I won't be able to pull it off securely enough. At that point, I'll give up. But for now, I want to understand things better and to actually implement those things, if possible and advisable. > "user" is ill-defined here (because there are multiple hosts involved).

I can't really say I understand what you're saying. More questions later, undoubtedly.
