Client IP Filters
The Router can be configured to restrict access to the Internet, email, or
other network services at specific days and times. Restriction can be set
for a single computer, a range of computers, or multiple computers.
URL Blocking
To configure the URL blocking feature, specify the websites (www.
somesite.com) and/or keywords you want to filter on your network. Click
"Apply Changes" to activate the change. To complete this configuration,
you will need to create or modify an access rule in the client IP filters
section. To modify an existing rule, click the "Edit" option next to the
rule you want to modify. To create a new rule, click on the "Add PC"
option. From the "Access Control Add PC" section, check the option for
"WWW with URL Blocking" in the "Client PC Service" table to filter out the
websites and keywords specified.

start time, and end time that you want to filter on your

the "DHCP Client List". To enable this feature, select "Enable". Next, click
"Apply Changes" to save the settings.

behind the firewall, you can open the client up to unrestricted two-way
Internet access. This may be necessary if the NAT feature is causing problems
with an application such as a game or video conferencing application. Use
this feature on a temporary basis. The computer in the DMZ is not protected
from hacker attacks. To put a computer in the DMZ, enter the last digits of
its LAN IP address in the "Static IP" field and click "Apply Changes" for the
change to take effect. If you have only one public (WAN) IP address, then you
