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 the level of security of your Router.
To turn off the ping response, select “Block ICMP Ping” (1) and click “Apply
Changes”. The Router will not respond to an ICMP ping.

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”.
