Looking to find some way to set up multiple VPNs under a single OpenVPN Server, where external clients can only connect to other devices in the same network/group.
Open VPN Server (host) VPN Group 1 (10.0.10.x) -> Andy -> Bob -> Chloe VPN Group 2 (10.0.11.x) -> Dave -> Emma VPN Group 3 (...)
So in this example, Andy/Bob/Chloe are on one private network and can connect to each other, but cannot connect to Dave/Emma. In the same way, Dave/Emma can connect to each other, but not Andy/Bob/Chloe.
Is this possible? I couldn't find any examples in the OpenVPN docs...
