this info from filelist might help someof ya's get faster speeds
basically some popular default ports get blocked by isp's and they want you to change to some non standard ones.
I find as long as theres a large group of people in the swarm i usually get 150 to 200k downloads..as well the higher your upload steam the higher the priority you get to recieve files so if you cap your upload stream at 5k/sec you will always be low on the list of getting files from other clients.
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.
FileList 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 which means that bandwidth is limited and the speed suffers..
The blocked ports list include, but is not necessarily limited to, the following:
Direct Connect
411 - 413
Kazaa
1214
Gnutella
6346 - 6347
BitTorrent
6881 - 6889
In order to use use our tracker you must configure your client to use any port range that does not contain those ports (a range within the region 49152 through 65535 is preferable, cf. IANA). Notice that some clients, like Azureus 2.0.7.0 or higher, use a single port for all torrents, while most others use one port per open torrent. The size of the range you choose should be typically less than 10 ports wide. There is no benefit whatsoever in choosing a wide range, and there are possible security implications.
These ports are used for connections between peers, not client to tracker. Therefore this change will not interfere with your ability to use other trackers (in fact it should increase your speed with torrents from any tracker, not just ours). Your client will also still be able to connect to peers that are using the standard ports. If your client does not allow custom ports to be used, you will have to switch to one that does.
Do not ask us, or in the forums, which ports you should choose. The more random the choice is the harder it will be for ISPs to catch on to us and start limiting speeds on the ports we use. If we simply define another range ISPs will start throttling that range also.
