Section 3 - Configuration Firewall Settings A firewall protects your network from the outside world. The D-Link DIR-412 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. 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. DMZ Host: 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 field. 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. Firewall Rules: Use this section to create rules that deny or allow traffic from passing through the device. See the following page for information on how to create firewall rules.

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.
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
field. 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.
