3.5 Setting 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 36 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:

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.

If you do not know how to deactivate the software, consult your

Windows Help or the documentation that came with your

software or computer.
