Hi i've been reading on the uTorrent forums that if you set your bittorent client to use a port the ISP uses for VoIP or similar that the port will not be throttled.

From http://forum.utorrent.com/viewtopic.php?id=3912

"It appears port 1720 (a VoIP [Voice over IP] port) is being unthrottled by some ISP's, so you may have to check that out as well. Alternatively, if all else fails, you could try port 443, 80, 21, 110 and as a last resort, 25. But it's better if you could try to find out what ports your ISP uses for NetMeeting/VoIP/Xbox Live etc. This is a legitimate question and they should be able to answer you what ports they use for these services without any problem/suspicion. It could very well be possible that you can bypass their BitTorrent restrictions using these types of ports. Here's a handy list of ports and their common uses."


I'm currently using port 1720 but with no luck. Does anyone know what port Xtra uses for VoIP or XBOX Live?

Thanks. Nigel.

No suprise. Is there any port they don't throttle? Email - Port 25 Mabye?

What are the VoIP, PS2 and XBOX ports just out of curiosity?

Changing ports is a waste of time because it's not post based throttling. Xtra use Layer7 packet shaping which examines the first few bytes of a packet to determine the type of traffic rather than just the port used.

Changing ports can get around a firewall with port blocking but not L7 filtering.

Anybody know what happens with SSL encrypted P2P traffic? Is that classified as HTTPS/SSL traffic and passed at full speed?

It depends on the inspection they use.
