          all,<br>
          <br>
          running strongswan as a client carol against our ePDG moon, I
          just cannot get the EAP-AKA authentication working. <br>
          <br>
          The strongswan client rejects the EAP-REQ/AKA-Challenge coming
          from moon with an EAP-NAK. This is, what Carol tells me:<br>
