Ok, so I just recently switched over to a Macbook. On my Vista machine I have uTorrent with port forwarding setup to an open port on my router. I upload around my max of 240kbps or so when seeding torrents on my Vista machine. Using Transmission with the following settings: Port forwarded to same port, says open. Its connectable. All speed restrictions are off, with unlimited up and down bandwith I download numerous files and get my max download, and theres enough seeders that it should max my up connection but it doesn't it just won't connect to any peers at all. If I turn on my Vista machine using uTorrent, downloaded the exact same file I get at least 30-40 peers connecting & anywhere from 190-240 kbps seeding. It is the newest version of Transmission. My tracker is online & connectable. Same file on uTorrent works fine. (of course I turn off uTorrent and Vista when trying to use Transmission) I'm a noob to Macs but not to computers, I don't see anything I overlooked, is this just a general problem with Transmission, or am I trying too hard and over looked something simple?
