That is very nice and a long awaited feature!

I'm also going to give it a try since I have a radius server ready, supporting multiple EAP types for eduroam.

Since I can't find the following info easily on google, what kind of EAP does windows 10 client do when you setup an ikev2 VPN?
There is no interface to change/show security settings (PEAP/TTLS - MSCHAPv2/PAP) like it does for wifi and WPA2-Enterprise.
