Bittorrent shaping even with encryption

Hi, i want to know if this is possible.



Our isp monitors our bandwidth use, and if one exceeds 7GB in a month, they change your subnet to a 200.8.x.x/23



Bittorrent doesn't work, when it kind of works speed is less than



1kb/s, and connections get reset randomly, bringing irc, msn and java chats down.

However, http downloads work at full speed.



My question is, how do they know i am using bittorrent, if i am using encryption? Are they just looking for HTTP headers, and failing to find them, think i am using torrents?

Because Bittorrent uses other ports besides port 80, the default for http. Encryption only covers the payload of a packet, not its source, destination, and other useful details.

If you want more bandwidth, pay for it.

From whatever BT client you use, change the default port from 6881 to some arbitrary port like 16721. Then, enable encrypted downloads only. This might help.

I'm paying for an "unlimited" plan. There is no mention even in the small letter that if i exceed certaint amount, i will be capped.

In countries like yours, you would be able to sue. In countries like mine, you are stuck.

Fortunately your country doesn't have a different definition of "capped".
