Unable to block port 3306
I'm having Norton Internet Security version 126.96.36.199 on Windows Server 2012R2 Standard.
I set a rule at the top of mine NIS smart firewall rule to block all incoming and outgoing traffic over TCP/UDP port 3306 as seen in the screen capture below.
Somehow that doesn't do anything! The port 3306 can still be connected from external.
NIS is the only anti virus I am having on the computer.
Can someone please help me to to lock down this port for external communication?
