Raspberry PI4 as Gateway & private TTS Server combined


For a university project, in the area of FirmwareUpdateOverTheAir with LoraWAN, I would like to create a mobile LoraWAN infrastructure with a Raspberry Pi 4. That means to use the Ri 4 as a mobile server and gateway at the same time.

In the instructions at Installing The Things Stack | The Things Stack for LoRaWAN, the server hardware must meet the following requirements: A server with a recommended 4 virtual CPUs and 16GB RAM running Docker and Docker Compose*.
I think this only applies if the server is to work in the public network. But in my case the mobile infrastructure should set up a private network.

Has anyone had experience with this: private network, raspberry pi4 as server and gateway?
