Re: Block torrent

We cannot specifically block torrent traffic at this time.

 

There is a way that you can create a named ACL *.facebook.com and block traffic to that, but that is no guarantee facebook uses other URLs for data.  You would need a content filter for that.

Re: Block torrent

[ Edited ]

We had a problem with students using torrents on our school wireless network. We actually recieved notification that someone was pirating movies from our wireless network. I discovered then that we couldn't block torrents due to its rotating random ports.

 

After a little research I found out that most (not all) torrent programs reach out and touch on a set of default ports first before they started to rotate to other random ports. Said ports are tcp 6881-6889. So I created a policy that blocked those ports and then black listed the device.

 

It wasn't a perfect solution and I did "catch" a few legit users but for the most part it did the trick as black listed users had to come to IT services department to get taken off the list.

 

I hope this can help you!!
