The bittorrent protocol relies on being able to make incoming connections
to the host running the client (there is no server/client distinction
really - hence peer to peer).
The default port used by bittorrent is 6881. You should allow incoming
connections from all sources to this port. I'm not familiar with the
Rusty Russell firewall rules, but you should look for an example of
allowing incoming connections, probably along the lines of
"iptables -A INPUT -s .... -d ... -j ACCEPT".
You can probably change the port, and you may which to use a range
(for example 6881..6890) to allow multiple torrents running
simultaneously.
