Restricting Access From Your Network 3-3
v2.1, July 2007
Block all access to Internet browsing during a scheduled period by entering a dot (.) as the
keyword and then set a schedule in the Schedule menu.
4. You may specify one Trusted User, which is a computer that is exempt from blocking and
logging. Specify a Trusted User by entering that computer’s IP address in the Trusted User
fields.
Since the Trusted User is identified by IP address, you should configure that computer with a
fixed IP address.
5. Click Apply to save all your settings in the Block Sites screen.
Blocking Access to Internet Services
The WNR834B 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:
1. From the main menu of the browser interface, under Content Filtering, click Block Services.
