Section 3 - Conguration
SPI (Stateful Packet Inspection, also known as dynamic packet ltering)
helps to prevent cyber attacks by tracking more state per session. It
validates that the trac passing through the session conforms to the
protocol.
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 option to provide protection 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 System>NetworkSettings page so that the IP address of the DMZ machine does not change.

A rewall protects your network from the outside world. The D-Link DIR-601 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.
