Firewall Settings

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 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.
