3.7.3.5 DMZ Host
The DMZ (Demilitarized) Host feature allows one of the local computers to be exposed to the Internet. Designate a
DMZ host when:
 You wish to use a special-purpose Internet service, such as a 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 restrictions.
Warning: 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 local 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 local network, such as a Web server, is fielded by the W40. The W40
will forward this request to the DMZ host (if one is designated) unless the service is being provided by another PC in
the local network (assigned in Port Forwarding), in which case that PC will receive the request instead.
 To designate a local computer as a DMZ Host:
1. Click DMZ Host under the Firewall menu. The DMZ Host screen appears.

2. Enter the local IP address of the computer that you would like to designate as a DMZ host and select the
check box. Note that only one LAN computer may be a DMZ host at any time.
3. Click OK to save the settings.
You can disable the DMZ host so that it will not be fully exposed to the Internet, but keep its IP address recorded on
the DMZ Host screen. This may be useful if you wish to disable the DMZ host but expect that you will want to enable it
again in the future.
 To disable the DMZ host so that it will not be fully exposed to the Internet:
Clear the check box next to the DMZ IP designation, and click OK. To reinstate it at a later time, simply reselect the
check box.
3.7.3.6 Port Triggering
Port triggering can be used for dynamic port forwarding configuration. By setting port triggering rules, you can allow
inbound traffic to arrive at a specific LAN host using ports different than those used for the outbound traffic. This is
called port triggering since the outbound traffic triggers to which ports inbound traffic is directed.
For example, consider a gaming server that is accessed using UDP protocol on port 2222. The gaming server responds
by connecting the user using UDP on port 3333 when starting gaming sessions. In such a case you must use port
triggering, since this scenario conflicts with the following default firewall settings:
