Firewall Settings - D-Link AC750 User Manual

Section 3 - Configuration
A firewall protects your network from the outside world. The DIR-810L 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.
The firewall setup also features a Demilitarized Zone (DMZ) option, which will expose the selected clients completely to the
outside world.
Enable SPI:
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.
Anti-Spoof Check:
Enable this feature to protect your network from certain kinds of
"spoofing" attacks.

close if idle for 5 minutes.
