I'm presently downloading a torrent with the bittorrent-gui, which seems to be progressing fine. However, I've previously run into problems with azureus. Azureus is a bittorrent client. What's happening that bittorrent, itself, works fine, yet azureus doesn't work due to blocked ports? What is a port? Apparently bittorrent works regardless of blocked ports. What is it about azureus that's different? thanks, Thufir
