Encrypted torrents Defeat NBAR?

[tsoukalis]

Hi All

I Wondering if any ones has complete block traffic with encrypted Torrents.

When torrents is not encrypted NBAR is recognizes torrents traffic and is easy to block them , in other way when the client torrent (like utorrent) is enabled the encryption ,  NBAR does not recognize at all and is bypass my firewall

Any Solution for this?

Sorry for my english.

George,

I don't think there is anythign anyone can do against encryption short of doign man in the middle attack (quite computation intensive).

Several years ago I was doing some testing with AIP + encrypted torrent. Same thing no hits as soon as encryption was enabled.
