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 will be exempt from blocking and 
logging. Since the Trusted User will be identified by an IP address, you should configure that 
computer with a fixed IP address.
Blocking Access to Internet Services
The WPN824 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 that a time period is specified in the Schedule menu (see 
“Scheduling 
When Blocking Will Be Enforced” on page 5-5
).
