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-1565 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.
