You're talking about NAT discovery; this mod doesn't talk about how you figure that out, just how to support it if you do know it. You can trivially know it in a key distro protocol if you send your adr/port in the payload, so that the endpoint can see if it matches what is on the outside. Granted that won't work in a backward-compatible way (e.g., for BEHAVE), but key distro protocols don't have that limitation.
