Yes, the initiator can detect NAT, as the responder will not try any
other addresses, i.e. it always replies back to the address where
addresess are reversed.

This simply requires that we want to have option to turn NAT-T on /
off as a separate notify, as requested by initiator after detecting
NAT (and after consulting policy etc).
