Blocking P2P Traffic on Centos?
 

Hello, it's been a while I'm looking for solution to block entirely P2P traffic on my servers, some of my users do torrent on non allowed torrent servers. I'm getting abuse report from my provider regarding this issue and hoping me to add measures to prevent it from happening again. I've look around but didn't see any light.

Does anyone have experience in blocking p2p traffic on their server? Hoping for you guys to share the method of blocking it. Anyway I'm running Centos
