You can 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 IP
Address
fields.
Since the trusted user is identified by IP address, you should configure that computer with a
fixed IP address.

Blocking Access to Internet Services
The Wireless-G 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
