My company use sensors on doors to track activity and access control on the doors for many sites throughout the UK. We need to log this activity by sending UDP packets from the sensor's receiver to the public server via a 4G router where the data will be received and access control logs will be saved.
We had a solution were the receiver was programmed to send the data to the public servers static IP address and the router was set as the default gateway, therefor when the server was not found on the network it would be sent to the router and then sent to the server. However this means that if we changed server IP address we would have to reprogram every receiver we use in the UK on site which is not good practice.
Because of this we need a solution that comes from a routing rule of sorts that sends all data from the receiver to the public IP address of the server so that we can change the routing config remotely.
Any help would be appreciated
