Peer to Peer (P2P) Blocking and Exclusions Explained

Peer to Peer (P2P) networks are commonly used for file sharing and instant messaging. In most cases, P2P networks have no educational function and can potentially compromise your network. The Lightspeed Web Filter allows you to easily block all P2P traffic with the click of a button. We do, however, understand that at times P2P traffic is necessary (ex. Skype sessions, some types of internal and external messaging, etc.) We give you the option to add P2P exclusions to exclude specific external IP addresses and ports from being blocked as P2P traffic.

Blocking P2P Traffic

All P2P traffic can be easily blocked through the Web Filter.

1. Within the Lightspeed Rocket Console, navigate to Web Filter and then to General. Scroll down to P2P Controls and check the box next to Block P2P Networks. 

You have now successfully blocked all P2P traffic.

P2P Exclusions

You can use P2P exclusions to exclude specific external IP addresses and ports from being blocked as P2P traffic. The following steps will show you how to add, edit, and delete P2P exclusions.
