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:

1. Select either Per Schedule or Always

2. Click Apply.

3. If you want to block by schedule, be sure to specify a time period in the Schedule menu, as

described in

“Scheduling When Blocking Will Be Enforced” on page 2-6.

To specify a service for blocking:

1. Click Add. The Add Services menu will appear, as shown below:

Figure 2-3

2. 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.
