Hello
Is it possible to block Ultrasurf with new Application control, if yes how?

thx

There are some pre-built rules in the rules that can be enabled that do a good job in our testing. However, some have side effects like blocking SSL for non-SNI supporting browsers so if you have winXP machines on your network or non-SNI SSL software it may be blocked also.

I have tested pre-builts but no success. They are also blocking some web sites about banking.

Anyone have anything new for blocking Ultrasurf. I have been trying different rules in firewall and bandwidth control but no luck..

you should use Application Control.
