There's several ways to do it. In most cases, you would want to ensure your firewall is configured not to allow any of the peer-to-peer protocols through to the Internet. The firewall is the best and easiest location to enforce these sorts of changes.

Also, if the P2P software requires installation, the other possibility is of course to just take away users' elevated rights to their workstations. This will stop them installing software in the first place, meaning you would eliminate most of the P2P software with immediate effect. Users shouldn't have local Administrator rights on workstations anyway.

There's some articles below I've found; they look good and I suggest you have a read!

I'm using a PIX 515e. Is there any information on how to block through the Cisco Firewall?

Hi, thanks for the points. I just wondered why you awarded a 'B' grade?
No response? <sigh>
