A rewall protects your network from the outside world. The D-Link DIR-632 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 cam enable DMZ. DMZ is short for Demilitarized Zone. This option will expose the chosen computer completely to the outside world.
Select one of the following for TCP and UDP ports:
Endpoint.Independent.- Any incoming trac sent to an open port will be forwarded
to the application that opened the port. The port will close if idle for 5 minutes.
Address.Restricted - Incoming trac must match the IP address of the outgoing
connection.
Address.+.Port.Restriction - Incoming trac must match the IP address and port
of the outgoing connection.
Enable this feature to protect your network from certain kinds of spoong” attacks.
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 its 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.
