Block P2P (torrent, etc.) traffic on Linux VPN server

Hello, I have over 9 years experience as an Linux admin and have done this before. Please feel free to ask if you have any questions. Thank You

Hello, I can help block the default ports for those applications, which should prevent those who aren't technically aware from being able to use torrents. We can also block known torrent trackers which should help as well, and block the standard DHT ports as well. It's going to be very difficult to block this traffic based on traffic analysis because of the encryption, but port blocking should stop a majority of users from being able to torrent.

Hi anogrish, Since 1996 I'm using Linux (everywehere where is possible, home/work, server/desktop/tablet/laptop/phone) In my work we using Centos since 2009, which where some firewall rules can fulfill your requirements. Please consider, that I need temporary access to your server during check and setup. Regards, George.

I need more information about the block, any prefer software that doing on that or still none?. I am the linux system engineer, being doing setup an vpn, iptables, firewall across of the linux platform.
