routing torrents with multiple connections/adapters wireless/wired
 

I've done a fair amount of searching for an answer to this and have been unable to find anything helpful.

Running Fedora 13 and have it working great acting as my firewall/router/samba server etc.
The problem is the connection is shared by a fair number of us and the ISP is getting annoyed with the amount of torrent traffic. One of us has access to a wireless network and we'd like to figure out how to route some of the traffic through that without having to disconnect from the current network.
I put a wireless card in the fedora box and can connect to the wireless but then it messes up the current network and pretty much nothing works.

At the least if I could run a torrent client (e.g. ktorrent or whatever) on the Linux box and have it download through the wireless card on tcp port XXXXX I’d be happy. The torrent client and those tcp/udp ports can be dedicated to that wireless card, the rest of the network doesn't need to get involved if that makes things simpler.

Not looking for a step by step tutorial, just an explanation of what needs to be done and a shove in the right direction. My experience is limited to single WAN connections up to this point.

Thanks in advance to anyone that can help

I believe you can use IPtables to route based on protocol.
