We´re trying to block connections to Ultrasurf anonymous proxy. We´ve defined a rule to block all connections against 188.8.131.52/24 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.
create two sets of block rule
type = forward
and the other
type = input
should do the trick
