Issue: Hello Team, good day. we have recently purchased the Industrial Outdoor LoRa Gateway namely the RAK7249. This Gateway is Robust in terms of functionality and has proven its continuous operation on TTN, thumb up RAK team. In addition, we have recently noticed some unwanted LoRaWAN devices are connected to our GW and sending Uplinks causing unnecessary background mobile data usage (GW using mobile backhaul: SIM card with monthly data package), as a security measure can you please advise on the preventive measure to filter out the unwanted LoRaWAN devices?.
Any config that can be done at gateway level or at any other level.
Many thanks for your help.
