Setting MAC Address Filtering
The MAC address filter is a powerful security feature that allows you
to specify which computers are allowed on the network. Any computer
attempting to access the network that is not specified in the filter list will be
denied access. When you enable this feature, you must enter the MAC address
of each client (computer) on your network to allow network access to each.

Next, enter the MAC address of each computer on your network by clicking
in the space provided
(2)
and entering the MAC address of the computer
you want to add to the list. Click “Add”

Using the Web-Based Advanced User Interface
Enabling the Demilitarized Zone (DMZ)
The DMZ feature allows you to specify one computer on your network to
be placed outside of the firewall. This may be necessary if the firewall 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.
Note:
If your ISP subscription provides you with additional public (WAN) IP
addresses, additional computers can be placed outside the firewall provided
each computer uses a different public (WAN) IP.
To put a computer in the DMZ, enter the last digits of its IP address in the IP
field and select “Enable”. Click “Apply Changes” for the change to take effect.

WAN Ping Blocking
Computer hackers use what is known as “pinging” to find potential victims on
the Internet. By pinging a specific IP address and receiving a response from
the IP address, a hacker can determine that something of interest might be
there. The Router can be set up so it will not respond to an ICMP ping from
the outside. This heightens the level of security of your Router.
(1)
To turn off the ping response, select “Block ICMP Ping”
(1)
and click “Apply
Changes”. The Router will not respond to an ICMP ping.
