Setup:
- A Linux host PC (Ubuntu 18.04/20.04) Running an up-to-date Virtual Box.
- Guest: A headless Virtual server (Ubuntu 18.04/20.04)
- Valid VPN account with a 3rd party. (in my case: NordVPN)
Goal:
- Start the virtual machine (guest) headless as a service when booting the Host machine.
- The VM must be able to log in automatically as a service without manually providing account credentials
- The VM uses a bridged network so it has a reachable IP on the LAN
- Using the VM-IP as a gateway for devices that need a VPN connection.
- No other outbound connection possible for devices using this gateway when the VPN-connection to NordVPN goes down, No internet connection is available.
