passing through the session conforms to the protocol.

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.

Carry out the following to create a DMZ host:

A rewall protects your network from the outside world. The DIR-815 oers a rewall 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.

1. Check the Enable DMZ box.

2. Specify the IP address of the computer on the

LAN that you want to have unrestricted Internet

communication in the DMZ IP address eld. To

specify an existing DHCP client, use the Computer

Name drop-down to select the computer that

you want to make a DMZ host. If selecting a

computer that is a DHCP client, be sure to make

a static reservation in the Setup > Network

Settings page so that the IP address of the DMZ

machine does not change.

3. Click the Save Settings button to add the new

DMZ host.
