DMZ

The firewall supports virtual DMZ in single (LAN) port router models. Virtual DMZ redirects traffic to a specified IP address rather than a physical port. Because this redirection is a logical application rather than physical, it is called “virtual DMZ.”

Using virtual DMZ, a single node on the LAN can be made “visible” to the WAN IP network. Any incoming network traffic not handled by port forwarding rules is automatically forwarded to an enabled DMZ node. Outbound traffic from the virtual DMZ node circumvents all firewall rules. The DMZ feature allows a computer on your home network to circumvent the firewall and have direct access to the internet. This feature is primarily used for gaming. Under this mode of operation all network traffic received from the WAN that is not destined for a host specifically exposed through NAT or for a server exposed through Port Forwarding will be redirected to the designated DMZ host. If the DMZ feature is enabled, you must select the computer to be used as the DMZ computer/host.

This function is recommended for use only when you require this special level of unrestricted access as it leaves your Router and network exposed to the Internet with no firewall protection. To enable and configure the DMZ:

1.Select Setup>Firewall>DMZ from the left navigation pane of the Web interface. This displays the “Firewall DMZ Configuration” window.

2.Select one of the following DMZ enable options:
