Put a rule at the very top of your Global Rules list to block just that port and protocol and the IP address (if it is the same each packet) then don’t log it.

This way the firewall doesn’t have to use extra resources to sort thru the firewall rules for each packet until it hits the Block All IN rule at the bottom of the list.


Might block the IP adress completely, instead of just access to one specific port.You can also report him to his ISP, but he might use a fake IP adress.
