How to distribute the Internet (wan miniport pppoe) from a virtual machine (virtual box) to a host?

Question

virtual box

The bottom line is that on a win10 working laptop, it is not possible to connect to the provider via pppoe in any way.
It was decided to create a virtual machine from it, connect to the provider, and then distribute the Internet from the virtual machine to the host.
Actually, the first part of the idea was successfully implemented by using the "Network Bridge" connection type on the virtual machine, i.e. the virtual machine directly has access to the host network card, and then connects via pppoe and has Internet access.
How to provide Internet access on the host machine?

Answer 1

Is it all happening on the same laptop, both the virtual machine and the host?
