Hi i want to block CamFrog, 75GB+ of bandwidth a month with it, just want to know what port it uses. Thanks

Perhaps you can start by telling us more about CamFrog and what it does?

If you have access to a box you know is running it, you could use a network sniffer, or tcpview, to see what ports it's using when active.

However, I've found it easier to just ALLOW ports at the firewall, and implicitly block everything else. That way, unless I open the port an app uses (and I really only allow mail, web, and XBL traffic from my home network through the firewall outbound), it doesn't work anyway. Something you might consider.
