Firewall Settings - D-Link DIR-600 User Manual

Section 3 - Coniguration
A irewall protects your network from the outside world. The DIR-600 ofers a irewall 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.

Firewall Settings:

Check the Enable SPI box to enable the SPI (Stateful
Packet Inspection, also known as dynamic packet iltering)
feature. Enabling SPI helps to prevent cyber attacks by
tracking more state per session. It validates that the traic
passing through the session conforms to the protocol.
DMZ Host: If an application has trouble working from behind the
router, you can expose one computer to the Internet and
run the application on that computer.
Carry out the following to create a DMZ host:
1. Check the Enable DMZ box.
2. Specify the IP address of the computer on the
LAN that you want to have unrestricted Internet
communication in the DMZ IP address ield. To
specify an existing DHCP client, use the Computer
Name drop-down to select the computer that
you want to make a DMZ host. If selecting a
computer that is a DHCP client, be sure to make
a static reservation in the Setup > Network
Settings page so that the IP address of the DMZ
machine does not change.
3. Click the Save Settings button to add the new
DMZ host.
Note: Placing a computer in the DMZ may expose that computer to a variety of security risks. Use of this option is only recommended as
a last resort.
