8.2.3 The Priorities of Port Forwarding and DMZ Host
The port forwarding has higher priority than the DMZ host. When receiving a request
packet initiated from an outside user, the Device will firstly search the Port Forwarding
List to find out if there is a port forwarding rule matching the destination IP address and
port of the packet. If a match is found, the Device will forward the packet to the mapped
local host. Else, the Device will try to find out if there is an available DMZ host.
And the interface DMZ host has higher priority than the global DMZ host. Only when there
is no interface DMZ host available to the request packet, the Device will choose the global
DMZ host.
