jflash, sorry that you're still stuck in Pigsnot & still can't connect!
You seem to have tried just about everything, even port forwarding. It sounds a bit suss to me but I can't find anything about your ISP blocking p2p or using traffic shaping! You could try Bearshare Lite but stay with version 5.1.0 or older (there's a link for download of that version below)
