<p class="MsoNormal">The 3GPP TS 33.402 spec (rel12) chapter 8.2.2 (top of page 33) says that the first IKE_AUTH request sends the user identity (in IDi payload) and the APN information (in the IDr payload).
<br>
Looking at the Strongswan source, I did not find any implementation of sending the APN in the IDr ?<o:p></o:p></p>
<p class="MsoNormal">Looking at RFC 4306 for the packet format, there is no mentioning of APN.<o:p></o:p></p>
<p class="MsoNormal">Does anyone know if the APN is required, and what the IKE_AUTH message might use it for?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Related code: <o:p></o:p></p>

<p class="MsoNormal">- libcharon/sa/ikev2/tasks/ike_auth.c (method build_i)<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The comment in method build_i suggests that IDr is optional?<o:p></o:p></p>
