2.4.4 Port Map
Port mapping is to modify the data packet of one port of the network network to another
port and send it to the set IP address.
2.4.5 DMZ
This setting can modify the DMZ host settings. If you need a host on the LAN to use the
server, you can set the host IP address as the DMZ host. After being set as a DMZ host,
packets sent to the router on the network are automatically forwarded to the DMZ host, and
the host is also directly exposed to the Internet. May cause network security issues.
