    Unable to block Ultrasurf anonymous proxy connection.

    maitane

      Good morning,

       

      We´re trying to block connections to Ultrasurf anonymous proxy. We´ve defined a rule to block all connections against 65.49.14.0/24 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.
