Section 4 - Configuration
Sometimes you may want a computer exposed to the Internet for certain types of applications. If you choose to expose a computer, you can enable
Demilitarized Zone (DMZ). This option will expose the chosen computer completely to the Internet. This is not recommended for normal use.
Enable SPI:
Enabling Stateful Packet Inspection (SPI) helps to prevent cyber
attacks by validating that the traffic passing through the session
conforms to the protocol.
Enable DMZ: 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.
DMZ IP Address: Specify the IP address of the computer on the LAN that you want
to have unrestricted Internet communication. If this computer
obtains its IP address automatically using DHCP, be sure to make
a static reservation on the LAN > DHCP > DHCP Reservervation
page so that the IP address of the DMZ machine does not change.
Click Apply to save your settings, or Refresh to revert to your
previous settings.
