Set Up The Dmz Host - Arris SURFboard SBR-AC1900P User Manual

Set Up the DMZ Host

Caution: The gaming DMZ host is not protected by the SBR-AC1900P Wi-Fi Router 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 Host. That computer
will operate outside of the SBR-AC1900P firewall and allow remote access from the Internet to
your computer, gaming device, or other IP-enabled device. The DMZ Host feature will only
allow outside users to have direct access to the designated DMZ Host device and not your
home network.
To create the DMZ Host:
1. Click Advanced on the SBR-AC1900P Main Menu bar.
2. Click DMZ Host from the Advanced submenu options.
3. 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.
4. 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.
