Question what do you want to do?

1. peer to peer

or

2. use a server to share and distribute the game on a user or client PC

if 1 Windows only alow one vpn user to connect to another user so this will not work

if 2 a Windows Server do not like to share a user or client to another user or client so this will not work also

With Windows the Server needs to have the Game on that you want to share

  if you want to share a client you need software on the server to 'root' the other 'clients' to the 'serving client' ( the server is just a glorified rooter!  )

if you want to share the game on a PC you need software on that PC, to have multiple clients connect to it, as that windows only allow one vpn or remote at a time
