Firewall Settings - D-Link DIR-412 User Manual

Section 3 - Configuration
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.
