Just in case...
Please, do not port forward anything on your router. The Hubitat admin web page on the hub is not password protected. If you were to forward port 80, anyone could easily control your hub.
There is no reason to forward any ports.
If you’re trying to send LAN data to your hub, use port 39501. If you have a Device defined in Hubitat with a deviceNetworkID equal to the MAC address of the Sending device, the LAN packet will be sent to the corresponding device’s parse() method.
