I'm currently using MacOS as a host and Ubuntu as guests, and the guest can use network connection of the host. However although I set the network settings as NAT and paravirtualized network, it just cannot use the VPN of the host.
I tried VBoxManage modifyvm "myVM" --natdnsproxy1 on as well but it makes no sense and the guest still cannot use that VPN connection. Does any one know the reason of this or how to fix it?
