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-615 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.
