Reference Manual for the Double 108 Mbps Wireless Firewall Router WGU624 Blocking Access to Internet Services The WGU624 wireless router allows you to block the use of certain Internet services by PCs on your network. This is called services blocking or port filtering. The Block Services menu is shown below: Figure 5-2: Block Services menu 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 that a time period is specified in the Schedule menu. To specify a service for blocking, click Add. Content Filtering 5-3 M-10153-01

Blocking Access to Internet Services
The WGU624 wireless router allows you to block the use of certain Internet services by PCs on
your network. This is called services blocking or port filtering. The Block Services menu is shown
below:
Figure 5-2:

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 that a time period is specified in the Schedule menu.
To specify a service for blocking, click Add.
