Introduction
The TG-1 Gateway allows you to configure one local device as a De-Militarized Zone (DMZ) host. This
means that:
None of the TG-1 Gateway firewall rules will be applied to this device.
All traffic originating from the Internet will be forwarded to this devices unless there is a port forwarding
rule defined for this type of traffic. Port forwarding rules always have higher priority.
Use a static address for the DMZ host
Make sure that your DMZ host uses a fixed IP address. If you do not do this, the device might get a new IP
address after some time and the port forwarding rule will no longer be applied to the device and another
device may suddenly be acting as DMZ host.
