15.4 DMZ Host—Single IP Address Passthrough
In the Firewall Settings screen, select DMZ Host from the submenu options displayed at the left of the screen. A
warning screen will display the following message:
Any changes made in this section may affect your device’s performance and configuration.
Do you want to proceed?
Click Yes to proceed.
15.4.1 Enabling DMZ Host
If you clicked Yes, in the preceding warning screen, the following DMZ Host screen will be displayed. The
demilitarized zone (DMZ) feature allows you to select one device on the LAN that will share the WAN-assigned IP
address. By enabling DMZ, the selected device becomes visible on the Internet. Network Address Translation
(NAT) and Firewall rules do not apply to the device configured for DMZ. If you are using Bridge protocol, you will
not be able to configure DMZ Host in the Router.
IMPORTANT:
1. Before you configure DMZ Host, configure your PC settings to obtain an IP address from VersaLink
automatically. If needed, refer to your computer’s Windows help screen for instructions.
2. If you have previously enabled Public LAN, you will need to disable Public LAN and enable the DHCP for
Private LAN and the Private LAN settings before you configure DMZ Host.
3. DMZ Host and Static NAT are mutually exclusive features. Before you enable DMZ Host, confirm that Static
NAT is disabled. If needed, refer to section 15.6.2 for details on disabling Static NAT.
