Yes, source address of encapsulating packet, and since it's an ACP, and since
the proxy negotiated via GRASP with the registrar, the registrar already

I think it's a MITM attack for the proxy to add any information to the secure part.
Any information not under the security enclosure may be untrustworthy.
