(first of all - sorry to post a torrent question, since its so hard to troubleshoot) I use transmission on my macbook pro with an airport extreme router, port 51411 forwarded to my macbook with a static IP. i use peer guardian as well. up until 2 weeks ago, it worked fine. then i moved to a new apartment, got a new ISP, and now i can't get downloads to actually start (90% of the time. oddly, 1 or 2 worked), even when i know there are a lot of seeders. BUT - when i use transmission away from home (EVDO connection) it works, even though there's no port forwarding. i tried turning off port forwarding, turning it back on - didn't work. i tried deleting all the preference and temp files for Transmission and starting fresh - didn't work. i tried using a different BT client (FireTorrent addon for firefox) and it worked. Current Preferences in Transmission: -no bandwidth limits -prefer encrypted peers -prevent known bad peers from connecting -enable peer exchange for public torrents -use port 51411, automatically map port any ideas?
