The number chosen for the uTorrent port is not that important (other than avoiding the ports commonly blocked by ISPs: 6881-6999). What is important is clearing that port (forwarding) through any firewall, software or hardware (router) on your system. A firewall will block uTorrent communications (as it should) unless an exception is made to allow uTorrent.
