Most vpn settings are forced by the server side. And assuming the server admin is the hacker, then they're going to allow that... Or if you mean the clients to communicate with each other.. yeah that's a crazy way to have it configured unless it's needed that way, but wouldn't surprise me if some have it configured that way.
