NETGEAR RangeMax™ NEXT Wireless Router WNR854T User Manual
Restricting Access From Your Network 4-3
v1.1, January 2007
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.
— To specify a Trusted User, enter that computer’s IP address in the Trusted User box and
click Apply.
Blocking Access to Internet Services
The WNR854T router allows you to block the use of certain Internet services by computers on
your network. This is called service 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.
To block access to Internet Services:
• From the main menu of the browser interface, under Content Filtering, click Block Services.
— To enable service blocking, select either Per Schedule or Always, then click Apply. To
block by schedule, be sure to specify a time period in the Schedule menu. For scheduling,
see “Scheduling Blocking” on page4-5.
