let Windows Guests be equal (bridged) amongst Host's vpn connected

Post by nkat »

Hello!
Please, consider the following scenario
Windows 10 Home Edition Host, Windows Server 2019 Guest.
Host runs on 192.168.1.0/24, connects to 10.10.21.0/24 via OpenVPN
My questions is
What should be done for the Guest OS to be bridged to OpenVPN interface?

Thank you!

You can't bridge to a host VPN, as the latter is specifically designed to be a secure connection between two participants. If you bridge to a physical network then that makes your VM a third participant, therefore not allowed. Exactly the same rules apply as when using an ethernet switch, which a bridged connection effectively is. If you want to use bridged and VPN then the VM needs its own VPN client, or else the VPN would have to be implemented in a home router or similar setup.

If you use NAT mode then all your network I/O is routed through the host Internet stack, and in that case you do share the host VPN connection.
