DMZ host

4.5.3.1 Overview
The default DMZ (De-Militarized Zone) host feature is helpful when you are using some online
games and video conferencing applications that are not compatible with NAT (Network Address
Translation).
Choose Advanced Setup > NAT > DMZ Host to enter the configuration page.
DMZ Host IP Address: The IP Address of the device for which the firewall of the modem router is
disabled. Ensure that the IP address is a static IP address. The DMZ host should be connected to a
LAN port of the modem router.
A DMZ host is not protected by the firewall of the router. A hacker may leverage the

DMZ host to attack your LAN. Therefore, enable the DMZ function only when
necessary.
Manually set the IP address of the LAN computer that functions as a DMZ host, to

prevent IP address changes, which lead to DMZ function failures.
Security software, antivirus software, and the built-in OS firewall of the computer may

cause DMZ function failures. Disable them when using the DMZ function. If the DMZ
function is not required, it is recommended that you disable it and enable your
firewall, security, and antivirus software.
