P2P blocking

Abdul Qadir Zakiuddin · ‎04-30-2009

I have 2821 router and ASA 5520 installed in my university. Task of router is just to pull internet bandwidth, while security ad control is performed by the ASA. Students usually use bypass proxy sites and P2P downloaders to download unnecessary and irrelevant things, thus choking the bandwidth. Can anybody tell me a solution for:

1) URL blocking on 2821 router or ASA 5520.

2) P2P blocking on 2821 router or ASA 5520.

Below are some config examples for url & p2p blocking in the ASA

However if you have a proxy server and your students are bypassing it - the solution is simple.

Confiugure the ASA to ONLY allow the Proxy server to access internet content HTTP/HTTPS services. Obviously allow other critical services, Email, DNS, SMTP etc.
