Why do I get a “rejected by tracker – Port xxxx is blacklisted” error?
Your client is reporting to the tracker that it uses one of the default bittorrent ports (6881-6889) or any other common p2p port for incoming connections. This tracker does not allow clients to use ports commonly associated with p2p protocols. The reason for this is that it is a common practice for ISPs to throttle those ports (that is, limit the bandwidth, hence the speed).
