When the device is behind a NAT enabled IP router, the local subnet is not accessible from the WAN side. This means that the device's local IP address cannot be used by other devices to communicate with it. The router can port forward BACnet packets to one device in the local network, but to do so other devices need to use the global IP for communication. The considerations and limitations for NAT usage are specified in BACnet standard Annex J.7.8. Thank you, Sami Pietikäinen, for the contribution!
