Services are functions performed by server computers at the request of client computers. For
example, Web servers serve Web pages, time servers serve time and date information, and game
hosts serve data about other players’ moves. When a computer on your network sends a request for
service to a server computer on the Internet, the requested service is identified by a service or port
number. This number appears as the destination port number in the transmitted IP packets. For
example, a packet that is sent with destination port number 80 is an HTTP (Web server) request.
To enable service blocking, select either Per Schedule or Always, then click Apply. If you want to
block by schedule, be sure to specify a time period in the Schedule menu. For scheduling, see
“Scheduling When Blocking Will Be Enforced” on page4-4.
To specify a service for blocking, click Add. The Block Services Setup menu appears, as shown
below:
From the Service Type list, select the application or service to be allowed or blocked. The list
already displays several common services, but you are not limited to these choices. To add any
additional services or applications that do not already appear, select User Defined.
