Hi Kathleen, Yes, this is referring to how the existing NAT detection works in IKEv2:
https://tools.ietf.org/html/rfc7296 Section 2.23. NAT Traversal o The data associated with the NAT_DETECTION_SOURCE_IP notification is a SHA-1 digest of the SPIs (in the order they appear in the header), IP address, and port from which this packet was sent. We can add a pointer to the section of the RFC.
