54D-Link DIR-412 User Manual
Section 3 - Configuration
SPI (Stateful Packet Inspection, also known as dynamic packet
ltering) helps to prevent cyber attacks by tracking more state per
session. It validates that the trafc passing through the session
conforms to the protocol.
Check the Enable DMZ box and specify the IP address of the
computer on the LAN that you want to have unrestricted Internet
communication in the DMZ IP Address eld. Use the drop-down
menu to specify a host that currently has a DHCP lease from the
DIR-412. If this computer has obtained its IP address automatically
using DHCP, be sure to make a static reservation on the System >
Network Settings page so that the IP address of the DMZ machine
does not change.
Use this section to create rules that deny or allow trafc from passing
through the device. See the following page for information on how to
create rewall rules.

A rewall protects your network from the outside world. The D-Link DIR-412 offers 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.
