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 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 its LAN IP address in the "Private
IP" field and click "Apply Changes" for the change to take effect.
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"
"Apply Changes". The Router will not respong to an ICMP Ping.
