DMZ Host
A DMZ host is a network device that is visible directly from the public Internet. This device has
unrestricted access to and from the Internet. When enabling this service the firewall settings for
the DMZ host will be disabled.
A DMZ Host is often setup when running software applications that use random port numbers and
do not function correctly when using Port Forwarding or Port Triggering. This may be useful if a
user wants to use some special service such as an Internet game or videoconferencing. Use this
option with caution, as the device setup as a DMZ Host is exposed to the public Internet. If
possible use Port Forwarding. Port Forwarding is a more secure method because it only opens
the ports you want and not all the ports as in DMZ hosting.
Setting up a DMZ Host
To setup a DMZ Host:
From the home page, click on the Advanced Setup tab. The Port Setting screen will be
displayed. The DMZ Host section is at the bottom of that screen:
