EAP-TTLS, not PEAP when using built-in Authentication Server

Hi gurus,

on FWF-61e, I provisioned WPA2 Enterprise, using local User Group.

Output of "diagnose wireless-controller wlac sta_filter" shows RADIUS messages, so, I must conclude that FortiOS implements an internal RADIUS server and exchanges EAP payloads (of EAPoW) messages with it.

Windows 10 Wireless properties showed that I was using EAP-TTLS EAP Method.

My question - is it possible to prefer other EAP methods, such as PEAP?

R's, Alex
