> NOTE: I am trying the tunnel with PSK and version is IKEv2.
> So is there fixed bytes of IKE_AUTH response which is expected by
> strongswan for PSK.
> And what does 'length of TRAFFIC_SELECTOR_SUBSTRUCTURE substructure list
> invalid' means, I tried finding it in RFC, but could not find the same.
