I have the need to isolate a virtual machine created with Virtualbox from the local network but I need to provide internet access to that machine. It is the first time that I face this kind of problem, different solutions came up in my mind:
- create a VLAN
- use a DMZ
- use a firewall in the host machine filtering communication in the virtual NIC
I would like to know what do you think about these solutions, which in your opinion is the best and why.
