Bisogna mettere le due interfacce in bridge o in internal
Codice:
Bridged networking This is for more advanced networking needs such as network
simulations and running servers in a guest. When enabled, VirtualBox connects
to one of your installed network cards and exchanges network packets directly,
circumventing your host operating system’s network stack.
Internal networking This can be used to create a different kind of software-based
network which is visible to selected virtual machines, but not to applications
running on the host or to the outside world.
