59D-Link DHP-1320 User Manual
Section 3 - Conguration
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 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.

A rewall protects your network from the outside world. The DHP-1320 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.
