Will help with the network setup in VirtualBox Debian 9?
I am using Debina 9 without a graphical interface. If a dedicated IP to access from outside. You need to do so that would be installed in a VirtualBox virtual machine running WinServer2016 had Internet access and could remotely connect via the internal RPD WS2016 (Not via RDP VirtualBox). That is saying to make a direct connection to the Internet from the virtual machine (the same not having lost access to Debian).
