Blocking Access to Internet Services

The WGT624 v3 wireless router allows you to block the use of certain Internet services by
computers on your network. This is called services blocking or port filtering. The Block Services
menu is shown below:
Figure 4-4
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.
