I would like to see you extend the video you just completed. (Great video BTW) With OpenVPN and Using Radius as the authentication server, also using the Radius for Wifi authentication. And how you would access Vlans with openVPN. Or maybe that would be pushing it. Just an Idea.
I have a FreeRadius Open VPN video and to access the VLAN’s you just add them to the “IPv4 Local network(s)” section in the OpenVPN config.
I might do a FreeRadius WiFi video but that does have some issues with certificates that become more complicated.
