Check the Enable SPI box to enable the SPI (Stateful Packet
Inspection, also known as dynamic packet ltering) feature.
Enabling SPI helps to prevent cyber attacks by tracking more
state per session. It validates that the trac passing through
the session conforms to the protocol.
Select one of the following for TCP and UDP ports:
Endpoint Independent - Any incoming trac 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 trac must match the IP address
of the outgoing connection.
Address + Port Restriction - Incoming trac must match the
IP address and port of the outgoing connection.
Enable this feature to protect your network from certain kinds
of “spoong” 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.

A rewall protects your network from the outside world. The DIR-815 oers 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.
