As the title says, when the VPN management was not delegated to macOS I could unplug from the wired network at my desk and connect to WiFi and the VPN would keep working. Now, if I do the same thing the VPN connection drops and I have to reauthenticate.
Is this intended behaviour or is it a bug? It was handy to be able to keep the VPN alive while going from wired to wifi and vice versa.
