// Consumers of this event should ALSO consume the `EvtLocalReachabilityChanged` event and interpret
// this event ONLY if the Reachability on the `EvtLocalReachabilityChanged` is Private.

	// Currently, it can be either a `EndpointIndependent NAT` or a `EndpointDependent NAT`. Please see the detailed documentation

	// how they impact Connectivity and Hole Punching.
