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). Looking at the Strongswan source, I did not find any implementation of sending the APN in the IDr ? Looking at RFC 4306 for the packet format, there is no mentioning of APN. Does anyone know if the APN is required, and what the IKE_AUTH message might use it for?
Related code: - libcharon/encoding/payloads/id_payload.c - libcharon/encoding/message.c - libcharon/sa/ikev2/tasks/ike_auth.c (method build_i) The comment in method build_i suggests that IDr is optional?
