Configuring a DMZ to Allow Access to All Ports of a Server
By default, the Router’s firewall prevents access from the Internet to your private
network. You can use the DMZ page to configure a Demilitarized Zone or
Demarcation Zone, which allows one local PC to be exposed to the Internet while
protecting the rest of your private network. Typically a DMZ is used for a special-
purpose service such as Internet gaming and video conferencing.
NOTE DMZ and Port Forwarding are used for similar purposes. However, Port Range
Forwarding can forward to a maximum of 10 ranges of ports on different PCs, while
a DMZ can forward all the ports for one PC.For information about Port Forwarding,
see Enabling Port Forwarding to Allow Access to Services, page 51.
