I > think we should promote it back. The gateway never sends any EAP identity requests at all. If such a request exists, it is sent by the AAA server. The gateway serves only as a pass-through. [SRINI] Text below from sec 3.16 of the bis hints that responder may send, but it says It should not. In RFC 4306, it was "SHOULD NOT", in the bis it is "should not". {{ Demoted the SHOULD NOT and SHOULD }} Note that since IKE passes an indication of initiator identity in message 3 of the protocol, the responder should not send EAP Identity requests. The initiator may, however, respond to such requests if it receives them. Thanks, Srinivas For that reason, there is typically no reason for the gateway to inspect the contents of the EAP payload.
