DMZ Host
You can configure one computer on your home network as the DMZ Host. The computer will
not operate outside of the SBG6400 firewall. This allows all port forwarding requests to go
through the DMZ Host. You can set up a separate subnetwork for remote access from the
Internet to your computer, gaming devices, or other IP-enabled device so that your home
network is not exposed to hackers or other external attacks from the Internet. Outside users will
only have direct access to the designated DMZ Host device and not your home network.
If you set up a computer as the DMZ Host, remember to set the IP address back to zero (0)
when you are finished with the needed application, since this computer will be exposed to the
Internet. Although the computer is protected from Denial of Service (DoS) attacks via the
SBG6400 firewall, it is still exposed to the Internet.
