6.1.6 Configure a DMZ Host

Introduction
The Gateway allows you to configure one local device as a De-Militarized Zone (DMZ) host. This means that:

None of the Gateway firewall rules will be applied to this device.

All traffic originating from the Internet will be forwarded to this device unless there is a port forwarding rule
defined for this type of traffic. Port forwarding rules always have higher priority.
Use a reserved IP address for the DMZ host
Make sure that your DMZ host uses a fixed IP address. If not, the device might get a new IP address after some
time through DHCP and the port forwarding rule will no longer be applied to the device and another device may
suddenly be acting as DMZ host. For more information, see
How to configure a device as DMZ host
1. Go to the Admin Tool (http://10.1.10.1), using a computer or device that is currently connected to your
Gateway (either wired or wirelessly). For more information, see
