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. 

--> AH, this is the possible Problem i think... :-/

Is the AAA PEAP certificate the same that you use to authenticate the gateway? 

--> no, there is a separate Certificate for our RADIUS Server, inside the log I see that the RADIUS Server shows his certificate to the client, but the client ignores it...

Does your AAA expect a client certificate to do mutual PEAP authentication before running the inner EAP method?

--> I think so. (is it possible to configure this inside the Ubuntu-strongswan-nm (compiled from source) ?
