Set Up the DMZ Host
WARNING!
The gaming DMZ host is not protected by the SBG6900-AC gateway firewall. It
is exposed to the Internet and thus vulnerable to attacks or hacking from any computer
on the Internet. Consider carefully before configuring a device to be in the DMZ.
You can configure one computer on your home network to be the DMZ. That computer will
operate outside of the SBG6900-AC firewall and allow remote access from the Internet to your
computer, gaming device, or other IP-enabled device. The DMZ feature will only allow outside
users to have direct access to the designated DMZ device and not your home network.
To create the DMZ Host:
1.
Log in to the SBG6900-AC Web Manager.
2.
Click Advanced on the SBG6900-AC Main Menu bar.
3.
Click DMZ Host from the Advanced submenu options.

4.
Enter the last one to three digits (from 2 to 254) of the IP address of the computer or
gaming device that you are setting up as the DMZ host.
5.
Click Apply.
Note
: Remember to reset the IP address back to
0
(zero) to close all the ports when you are finished
with the needed application. If you do not reset the IP address, that computer will be exposed to the
public Internet.
