Blocking Services (Port Filtering)

You can block the use of certain Internet services by computers on your network. This is called
services blocking or port filtering.
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.
