Lock the port

Hello, how can I lock a specify port with Comodo?
for example if i would like to lock the port 1000 in enter, in exit or both what should I do?

Go to Firewall > Advanced > Network Security Policy > Global Rules > Add… >
then choose if you would like to block or allow (or both), what protocols to block/allow (TCP, UDP, or both), then set the following:

Source Address: Any
Destination Address: Any
Source Port: ‘A single port’, port 1000
Destination Port: ‘A single port’, port 1000
