What is Port Mapping:

Port mapping is to map a port of a host in the internal network to a port of a host in the external network to provide the corresponding service. When a user accesses this port of an external IP, the server automatically maps the request to the machine inside the corresponding LAN.

Note that the port forwarding is from the external port of the router to the device port of the internal network.
