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.

Right.
You only ever have port after a meal, and it should have been decanted for a decent period beforehand. At the table, you always pass the port to the left- you're never allowed to pass it across the table or anything. If the port comes to you and you don't want any at the moment, make sure you pass it on to the person next to you- sitting on the port is very bad form.
If there are two specific ports going round the table, they should both start at different ends of the table. If they meet, that shows that the person they've met at is clearly sitting on the port too much.
Always use seperate glasses for different ports.

Damn, you got to it first. And did it better than I would have, too.

*hugs you twice over*

[glamwhorebunni.livejournal.com]

Got it the wrong way round first time tho :P

[glamwhorebunni.livejournal.com]

Well, not really "wrong".
It's just that I was using method B, where it's all to do with the *shape* of buoys, not their colour.

I'll shut up now.

Of course, the alternative post would have been:

Right, this is following the British maritime code. Not sure if the US sails on the other side as well as drives on the other side...

Basically, a river channel will have buoys marking it out. When inbound to a port, you should keep red buoys to your left ('port') and green buoys to your right ('starboard'). When outbound, do the opposite.

Some buoys such as the spherical mainly-red-but-with-a-horizontal-green-stripe buoys mean that you should treat them as a red buoy unless you have a shallow vessel and good knowledge of the area. Conical mainly-green-with-red-stripe buoys mean the opposite, obviously.

If you want to check the outbound access for a specific port, look at any decent up-to-date maritime chart of the area and it will show you the location and colour of all the buoys.
