Section 3 - Conguration
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 trac passing through the session conforms to the
protocol.
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.
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.
Specify the IP address of the computer on the LAN that you want to
have unrestricted Internet communication. If this computer obtains it’s
IP address automatically using DHCP, be sure to make a static reservation
on the Setup > Network Settings page so that the IP address of the
DMZ machine does not change.

A rewall protects your network from the outside world. The DSL-2770L oers 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.
