i have mcaffe, and so far its been the only program that hasn't blocked access for my programs such as bearshare and bitcomet. The problem is, bitcomet doesnt work any more

(bitcomet = bit torrent)
so i was trying out some others, like uTorrent and Azureus, but they need a listening port. I disable my firewall and everything and i get a NAT error!
what other torrent programs are there that could work..?
and btw, i have a wireless card, connecting to an apple airport extreme base startion. the apple isnt a gateway computer or anything like that
oh, and go to 'heck' if you say im using it illegally or to get illegal/copywriten files
