3.4 How to Set Up a DMZ

If you are playing a game or using an application that requires a specific port or ports to be open, go to page 19 for instructions on setting up a Virtual Server. A virtual server can have a maximum of 20 ports open.

If you need more than 20 ports open, or you don’t know which ports to open (some games or applications like NetMeeting use “dynamic” ports, meaning that the ports used by the game are constantly changing, so it is not possible to set specific ports), you have to set up what is called a DMZ (Demilitarized Zone).

To set up a DMZ, you need to make all four of the settings in the chart below. You make these settings on the computer where you set up the DMZ, no matter whether the computer is a Windows, Macintosh, or Linux computer.

Important! If your computer already has firewall software installed: If you have third-party firewall software installed on your computer, such as the Windows XP firewall, you may need to deactivate it before opening ports by setting up a virtual server or a DMZ. If you don’t, your computer may block the ports you are trying to open.

Click the Advanced Setup icon, then click LAN Settings. There you will see the starting and ending range of the X5v’s dynamic (DHCP) LAN IP
