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.
Enable this feature to protect your network from certain kinds of
“spoong” attacks.
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.
Allows multiple machines on the LAN to connect to their corporate network using PPTP protocol.
Allows multiple VPN clients to connect to their corporate network using IPSec. Some VPN clients support traversal of IPSec through
NAT. This ALG may interfere with the operation of such VPN clients. If you are having trouble connecting with your corporate network,
try turning this ALG o. Please check with the system administrator of your corporate network whether your VPN client supports
NAT traversal.

A rewall protects your network from the outside world. The DIR-826L 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.
