    I'd also like someone to clarify this question. From what I
    understand currently, using EDH for IKE_SA is a PFS as it is in
    "usual" SSL/TLS (e.g. in HTTPS) — you'll get new EDH key for every
    new IKE_SA negotiation.<br>
    But EDH in CHILD_SA is what you would call "key rotation". If you
    use EDH in CHILD_CA, you'll get new EDH key every rekey, i.e. every
    hour or so.<br>
    Is this correct?<br>
