D-Link DIR-845L User Manual
Section 3 - Configuration
SPI (Stateful Packet Inspection, also known as dynamic packet filtering)
helps to prevent cyber attacks by tracking more state per session. It
validates that the traffic passing through the session conforms to the
protocol.
Enable this feature to protect your network from certain kinds of
“spoofing” attacks.
Select one of the following for TCP and UDP ports:
Endpoint Independent - Any incoming traffic 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 traffic must match the IP address of the
outgoing connection.
A Port Restriction
- Incoming traffic must match the IP address
and port of the outgoing connection.

Firewall Settings
A firewall protects your network from the outside world. The DIR-845L offers a firewall 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.
