videoconferencing applications that are not compatible with NAT (Network Address Translation).
Choose Advanced> 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.
To configure the DMZ function, perform the following procedure:
Step 1 Click Add.
Step 2 Set DMZ Host IP Address to an IP address of the DMZ host.
Step 3 Click Save/Apply.
