There is nothing wrong on your Gateway; it just forwards EAP authentication between clients and your AAA. You should take a look at your client and the terminating RADIUS server log.

The problem probably is that your AAA is proposing PEAP. On NM, you can configure a single server certificate only. Is the AAA PEAP certificate the same that you use to authenticate the gateway? Does your AAA expect a client certificate to do mutual PEAP authentication before running the inner EAP method?

Martin
