2.4.3 DMZ
DMZ is used to map the host address of the router's internal network to the external network,
so that the internal network's host can provide network services. After setting up the DMZ
host, the external network's access to the router's IP address will be forwarded to the
corresponding DMZ host.
Ordinary SIM cannot use the DMZ function due to operator restrictions. Some special
network cards and IoT cards can use the DMZ function. Selecting the "80 port" button means
that port 80 is not forwarded. Uncheck the "80 port" button, then forward all ports.
