The demilitarised zone (DMZ) option is for forwarding IP packets from the Internet that are not meant for any of the applications configured in the virtual server table. These packets are forwarded to a designated DMZ host computer. While a virtual server can only forward (redirect) a limited number of services (ports), DMZ hosting allows all the services (ports) running on the DMZ host to be accessible externally.
To configure the DMZ, enter the DMZ host IP address of the computer that will function as the DMZ host. Click Apply to save the DMZ address.
To deactivate the DMZ feature, clear DMZ host IP address field and click Apply.
