Question

Debian

It is necessary to make sure that the virtual machine running WinServer2016 installed in VirtualBox has Internet access and can be remotely connected via the internal RPD WS2016 (Not via RDP VirtualBox). That is to say, make a direct connection to the Internet from the virtual machine (also without losing access to Debian).
Is it possible to? What do we have to do?
