MANUALLY CONFIGURING YOUR ROUTER
DMZ (Demilitarized Zone)
If you have a client PC that cannot run an Internet application properly
from behind the firewall, you can open the client up to unrestricted
2-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 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 to which WAN IP address the DMZ host will be
directed. Type in the WAN IP address to which you wish the DMZ host
to direct, 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 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.
