Blocking UltraSurf

I'm looking for information on how to block Ultrasurf. So far all the information I have found has been incredible wrong. Example, everyone is saying to block port 9666 on your firewall, however 9666 is a local port it is using that never goes outside the computer. I will go into more detail if I need to later. There are a few places I have found where people are saying their companies or school districts have found a block for this program. If anyone has any information please let me know.

Thanks, Dusty

 

I ran across a product called NetSpective (? something like it) that blocks Ultrasurf, openvpn, etc... skype and other encrypted protocols. You may look there.
