Application Patrol stops working after upgrading Flex500 to firmware 5.30

Andrea_VV

Hello. We have Flex500 controlled via NCC. Yesterday I've upgraded the firewall to firmware 5.30, and the security policy with some application patrol had a working malfunction: it stops ALL the traffic of our LAN, not only the application traffic it was designed to stop. I have had to disable the security policy. In firwmare 5.21 it worked fine.
I've done some test, and I'm not able to adopt any application patrol or content filter policy. They stop ALL the traffic, non only the traffic directed to some sites/services.
Any suggestion? Thank you in advance
