    Unable to block Ultrasurf anonymous proxy connection.


      Good morning,


      We´re trying to block connections to Ultrasurf anonymous proxy. We´ve defined a rule to block all connections against subnet, wich is the subnet Ultrasurf uses to conect against.


      With this rule, many connections matches with the rule and they´re suposed to be dropped by the firewall but in deed, if we try to use Ultrasurf, we can jump the filters without problems.


      So, how should I define the rule to block this proxy conention?


      I would appreciate your help very much.


      Thanks in advance.

      Best regards.
