Controlling whether networked computers can share messages, files, and printing
Network services let networked computers send and receive messages, shared files, and print. You can create a firewall rule that allows or blocks network services.
You can add a custom network service through a firewall rule. However, that network service is not added to the default list. You cannot access the custom service from any other rule.

On the Firewall Policy page, click .
On the Rules tab, in the list, select the rule you want to edit, right-click the Service field, and then click .
