Hi James,

I don't see much of an error here. The client is successfully
authenticated and the SA is set up. The client retransmits the IKE_AUTH
request, most likely because the first IKE_AUTH response gets lost.

Please check where/why the message gets lost if this is reproducible,
and what the error is on the client.

Regards
Martin
