6.5.3 DMZ
DMZ (De-Militarized Zone) Host is a host without the protection of the router’s firewall. It
allows a computer to be exposed to unrestricted two-way communication with the
Internet. You should only use this feature when the Port Forwarding function fails to
make an application work.
Warning: Setting your computer as a DMZ host exposes it to various security
vulnerabilities. This feature should be used only when needed.
DMZ: Select to enable or disable DMZ.
Source IP Address: Select any source IP address or specify a source IP address.
Host IP Address: Specify the host IP address.
Note: Any DMZ host should have a new static IP address assigned to it because its IP
address may change when using the DHCP function.
Click Apply and OK to save the setting.
