Whitelisting of clients with common name (CN) or certificates
I'm using VPN Gateway (VpnGw1) with openVPN configuration and Azure certificates. Currently there is no way to allow a client connection based on a certain condition, because in general all clients with a valid certificate can connect to the VPN Gateway. As there is a way to blacklist clients via revocation list, it would allow interesting use cases if whitelisting of clients is possible too.
For openVPN this could be done quite easily with the '--tls-verify' plugin, but i guess there i no way to customize the openVPN server configuration / add plugins.
