yes. Just a regular linux box as the router, sitting behind 
a DSL modem in bridge mode.

no. doing anything special. I remember when I set it up that 
I didn't really know what was going on with bittorrent. It 
seemed to work OK in both directions and I didn't really 
know what the slowdown was about, but it wasn't a great 
problem so I forgot about it.

I just ran the NAT test on azureus and found that port 47518 
(udp/tcp) is blocked. Presumably I ran this test when I 
installed it. If it failed then I probably said "well it 
it's uploading and downloading, what else do I need?".

let me try that.

If it needs these, how can it work at all if I don't have 
them?

Thanks
