• If you wish to block all Internet browsing access during a scheduled period, enter the keyword
“.” and set the schedule in the Schedule menu.
To specify a Trusted User, enter that computer’s IP address in the Trusted User box and click
Apply.
You may specify one Trusted User, which is a computer that is exempt from blocking and
logging. Since the Trusted User is identified by IP address, you should configure that
computer with a fixed IP address.
Blocking Access to Internet Services
The WPNT834 router allows you to block the use of certain Internet services by computers on
your network. This is called service blocking or port filtering. The Block Services menu is shown
below:
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 page 5-5.
