Section 3 - Configuration
A firewall protects your network from the outside world. The D-Link DIR-600 offers a firewall type functionality. The SPI feature helps
prevent cyber attacks. Sometimes you may want a computer exposed to the outside world for certain types of applications. If you choose
to expose a computer, you can enable DMZ. DMZ is short for Demilitarized Zone. This option will expose the chosen computer completely
to the outside world.

validates that the traffic passing through the session conforms to the
protocol.
Enable DMZ Host:
If an application has trouble working from behind the router, you can
expose one computer to the Internet and run the application on that
computer.
Note: Placing a computer in the DMZ may expose that computer to
a variety of security risks. Use of this option is only recommended
as a last resort.

IP Address:
have unrestricted Internet communication. If this computer obtains
its IP address automatically using DHCP, be sure to make a static
reservation on the Setup > Network Settings page so that the IP
address of the DMZ machine does not change.
