    how to block ultrsurf application.

    Amit Divekar

      Hello Guys,

                       I have found out this application called ULTRASURF,which bypasses all possible firewalls.

      The native firewall on vista is able to block this application & some software firewalls as zonealarm are able to detect it

       

      It works on tcp port 9666,but just blocking this port doesn't help as it work on both port 80 & 443.

      it also uses a lot of open proxies which are:-

      Any updates as to how do we block this,its giving me sleepless nights as keep thinking of ways to block it at all possible times.
