The DMZ (Demilitarized) Host feature allows one local computer to be exposed
to the Internet.
Designate a DMZ host when:
 You wish to use a special-purpose Internet service, such as an on-line game
or video-conferencing program, that is not present in the Port Forwarding list
and for which no port range information is available.
 You are not concerned with security and wish to expose one computer to all
services without restriction.
A DMZ host is not protected by the firewall and may be vulnerable to attack. Designating a DMZ host
may also put other computers in the home network at risk. When designating a DMZ host, you must
consider the security implications and protect it if necessary.
An incoming request for access to a service in the home network, such as a
Web-server, is handled by the Router. PRG AV4202N will forward this request
to the DMZ host (if one is designated) unless the service is being provided by
another PC in the home network (assigned in Port Forwarding), in which case
that PC will receive the request instead.
