I got a Gateway that receives LoRa messages and forwards them via LTE to the internet.
I don´t want everybody to use my LTE-Volume. So I am trying to set up a Firewall that doesn´t forward these unknown devices.
Setting up a filter for every device will be very time consuming due to there are many. But they all have in common that they provide their AppEUI (some Hex values) during transmission.
Is it possible to create a Firewall rule that searches for this hex Value and just forewords the packages including them, or to write a script that does the job?
Thanks
