My weird use case is to chain a virtualbox host only adaptor to another. I\u2019m essentially going from one VM to another. The second vm is a debian box that will run openvpn and tunnel out. The goal is that if the Debian VM isn\u2019t running, there\u2019s no internet access.<br>
<br>
I\u2019ve followed a tutorial and I got some of it to work.<br>
<br>
I\u2019m willing to pay for the tutorial. As such knowledge is highly specialized, $100 an hour with a 2 hour minimum sounds amenable.<br>
<br>
Cheers,<br>
