Hi,
Is there a way to stop bittorrent. I have tried using match statements in class/policy-maps with no luck.
I've moved on to using FPM but still no luck. I believe the newer torrent clients encrypted communications.
Any Ideas?
Regards,
Steve

You can create an ACL on the router to block P2P ports such as 6881 (Bittorrent). Following link may help you

You can use NBAR within IOS to block bittorrent. Here's an example of how to do it:
