I have a question about the mqtt piece as part of the docker-compose setup. I see here that port 1883 is exposed on the host https://docs.netmaker.org/server-installation.html#compose-file-annotated which makes sense. However, in the architecture section it talks about the mqtt traffic being encrypted by wireguard https://docs.netmaker.org/architecture.html#mosquitto-broker-mqtt and golang. How is the traffic flow working for this then? Does every netclient have a wg tunnel to netmaker? If so, why expose the port on the host? Haven't managed to get it working yet so I can't look at my own setup 😉
