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.
