Your best bet is port filtering. You apply a block on the required ports on the inside of your firewall. It depends what firewall you have as to how you configure it...

The most common approach would be to implement a proxy server. We use a proxy "appliance" box that is made by BlueCoat (www.bluecoat.com).

This gives you the ability to limit what kinds of Internet connections can be made, and it allows you to filter addresses, etc. Depending on your budget, it also can make use of services like WebSense. WebSense maintains a list of web sites that are "questionable" and will automatically block users from being able to access them.

Hope this helps, please let me know if you have any more questions.
