The detailed steps of each project are not particularly clear. But following the steps below, you should be able to connect remotely smoothly.

1? Virtual machine network, using NAT.

In this network, the networking of virtual machines is completed through the host. External networks, including hosts, cannot connect to the virtual machine.

Therefore, it is necessary to map ports.

2? Port mapping:?

The port mapping in the figure means: If it passes? 127.0.0 1 accesses the host's port 3382, and the host will send this request to the virtual machine's port 3389.

3? Open the remote desktop of the virtual machine.
