did dyou find something that works for you - I want to create the same solution. The boat shall automatically send data to IOT-Servers and I want to access via VPN checking cameras and settings on board.
Primary connection is marina hotspot, second and third SIM-Cards.
Unfortunately, I bought the RUTX11 already - but it doesnt seem to work as the WAN-connection can only use mobile or wired interface (with the newest Firmware!?). Before one could define it??
Thanks a lot
