Firewall

A firewall protects your network from the outside world. The D-Link Gaming Router 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 cam enable DMZ. DMZ is short for Demilitarized Zone. This option will expose the chosen computer completely to the outside world.

SPI (Stateful Packet Inspection, also known as dynamic packet filtering) helps to prevent cyber attacks by tracking more state per session. It validates that the traffic passing through the session conforms to the protocol. When SPI is enabled, the extra state information will be reported on the Status > Active sessions page.

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.

Specify the IP address of the computer on the LAN that you want to have unrestricted Internet communication. If this computer obtains it’s IP address automatically using DHCP, be sure to make a static reservation on the Basic > DHCP page so that the IP address of the DMZ machine does not change.

Advanced > Firewall

After you’ve completed all modifications or deletions, you must click the Save Settings button at the top of the page to save your changes. The router must reboot before new settings will take effect. You will be prompted to Reboot the Device or Continue. If you need to make additional settings changes, click Continue. If you are finished with your configuration settings, click the Reboot the Device button.
