+- entering group authenticate {...} [eap] EAP Identity [eap] processing type md5 rlm_eap_md5: Issuing Challenge ++[eap] returns handled Sending Access-Challenge of id 249 to 196.0.4.18 port 1812

You're still have EAP-MD5 as default EAP method. Look thoroughly into eap.conf. There is default_eap_type setting in eap {...} section. This is default outer EAP method. You should set it to ttls. There is default_eap_type setting in ttls {...} subsection of eap {...} section. This is default inner EAP method for EAP-TTLS. You should set it to gtc. Restart freeradius after the change. You should see something like this when processing first Access-Request: [eap] EAP Identity [eap] processing type tls [tls] Initiate [tls] Start returned 1
