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.
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. If you are using multiple static WAN IP addresses, it is
possible to select which WAN IP address the DMZ host will be directed
to. Type in the WAN IP address you wish the DMZ host to direct to,
enter the last two digits of the IP address of the DMZ host computer,
select “Enable” and click “Apply Changes”.
Blocking an ICMP Ping
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 your
Router’s security level.
