5. Click Apply to save all your settings in the Block Sites screen.

The WNR3500L 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. Select Block Services under Content Filtering in the main menu. The Block Services screen 

displays.

2. Enable service blocking by selecting either Per Schedule or Always, and then click Apply. 

To block by schedule, be sure to specify a time period in the Schedule screen. For information 
about scheduling, see
