There are two computers in the LAN with port 3389 open.
Can't connect to any computer! You can only assign a port in the intranet to a port in the public IP (port mapping). Two machines can use different ports, such as one using 8888 and the other using 9999, which are all converted into 3389 ports of different hosts in the intranet, and the two hosts can be connected separately. . thank you
