How to distribute the Internet to a specific computer in the local network?

Question

VPN

There is a PC ( Win 7 ) on which the Internet is connected mainly via PPPoE, it also happens via a VPN (PPTP) connection, I would like to distribute it to one of the hundreds of PCs on the local network.
I made an incoming VPN connection, but after its creation, the Internet disappears on the main machine.
Only a proxy works, but I would also like to give the Internet not to a PC, but to a router, which unfortunately does not work through a proxy.
Tell me the normal way to distribute the Internet to the machine I need in the local network.

Answer 1

Instead of your computer, put a router and distribute the Internet from it to your first and second computers. The router must be smart.
