FreeRADIUS/EAP-TLS - eapol_test - lost at next steps

Ok, I am very close to getting my EAP-TLS setup working. I have created and verified certificates, I have configured FreeRADIUS to EAP-TLS. I finally tested with eapol_test (would have saved me a lot of time if I had done that from the start).

eapol_test against 127.0.0.1 port 18120 (inner-tunnel) works, eapol_test against FreeRADIUS_server_IP port 1812 fails.

Has anyone had this happen, if so, how did you solve it?

Comparing eapol_test outputs:

FAIL:
