Hie, As per my network policy, we have to block all torrent traffic from network. To do this, I used to block all ports above 1024 on my firewall/proxy devices. But due to this, many other applications which use non-standard ports are not able to function, specially the mobile applications and a wide community of users are complaining because of this.
So, is there any effective way of blocking torrents in my torrent?
A minimum number of ports, or few specific ports, or application level filtering?
We have Cisco Iron Port Security and Cisco ASA 5500 Firewall devices.
