Reference Manual for Cable/DSL Wireless Router WGR614
Content Filtering 4-3
• If the keyword “.com” is specified, only websites with other domain suffixes (such as .edu or
.gov) can be viewed.
• 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 PC’s IP address in the Trusted User box and click Apply. You
may specify one Trusted User, which is a PC that will be exempt from blocking and logging. Since
the Trusted User will be identified by an IP address, you should configure that PC with a fixed IP
address.
Blocking Access to Internet Services
The WGR614 router allows you to block the use of certain Internet services by PCs on your
network. This is called services blocking or port filtering. The Block Services menu is shown
below:
Figure 4-2: Block Services menu
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.
