I have very strange issue with Fortigate 50b IPS.
I have Kerio Connect mail server in my company, Yesterday i created firewall polikcy for it with ports as explained, my problem is custom Services/ports. I have created IMAPS/993 service/port added it to the policy but firewall dropping it. Actually firewall drops all custom services/ports i made. Predefined Services/ports work good.
Ideas? Why custom Services/ports not work?
