Anybody who wants to explain port forwarding to me in layman's terms should feel more than welcome to. Ditto for making sure specific ports have outbound access.

Sure. It's better than sending discussion questions to my history seminar. Ports are pretend things that are like TV channels. A router is a specialized computer that takes a lot of streams of information and separates them so the right things go where they should. What it seems like you want to do is to tell your router that when it sees information bound for port 27960 on any computer, it really wants to go to your computer so that you can host a Quake 3 game. Or 21 and an FTP server, or whatever. The number assignments are arbitrary, but they're mostly standardized. 80's for the Web. I forget what number Telnet is. Doesn't matter. Anyway, you usually do this by talking to your router through some web-based interface. On a Linksys router, you go to 192.168.1.1, and it'll let you do it from there, but if you have a different kind of router, then it'll be some other address. Outbound and inbound work more or less the same way.

That song is killer.

OK, that seemed like what I'd figured out for the inbound stuff, but there doesn't seem to be an option on the router for outbound. Specifically, I'm having trouble getting BitTorrent to recognize that I'm happy to open all the ports it could ever possibly want.

AFAIK, you shouldn't need to map outgoing ports because the outgoing port gets fowarded normally even if there are a lot of computers on the internal network. The confusion exists only on inbound data streams where the destination isn't obvious because several computers are using that port. AFAIK, if bit torrent is well designed, it should transmit its own incoming ports on a standard outgoing port on the server and work fine through a router/firewall from there.

You're trying to download files, right?

The firewall should take care of the outbound connections automatically. If BT isn't opening lots of connections and you have it set to do so it's probably that you are trying to connect to servers that are rejecting your connections, so you can't get up to the maximum # of connections that you theoretically support.
