Advanced DMZ Host Page

This page allows you to specify the default recipient of WAN traffic that NAT is unable to
translate to a known local PC. The DMZ (De-militarized Zone) hosting (also commonly
referred to as "Exposed Host") can also be described as a computer or small sub-network
that is located outside the firewall between the trusted internal private LAN and the un-
trusted public Internet. It prevents direct access by outside users to private data.
For example, you can set up a web server on a DMZ computer to enable outside users to
access your website without exposing confidential data on your network.
A DMZ can also be useful to play interactive games that may have a problem running
through a firewall. You can leave a computer used for gaming only exposed to the
Internet while protecting the rest of your network.
You may configure one PC to be the DMZ host. This setting is generally used for PCs
using problem applications that use random port numbers and do not function correctly
with specific port triggers or the port forwarding setups mentioned earlier. If a specific PC
is set as a DMZ Host, remember to set this back to zero when you are finished with the
needed application, since this PC will be effectively exposed to the public Internet, though
still protected from Denial of Service (DoS) attacks via the Firewall.

Setting Up the DMZ Host

1. Enter the computer's IP address and select Enable checkbox.
2. Click Apply to activate the selected computer as the DMZ host.
