Hi @nogu -
This should be possible, but you’ve got the direction of the BaseStation and BlueBoat Mikrotik radio backwards- the BaseStation is the AP, and the Boat is the client (this proved to work much better when operating at long ranges.)
Perhaps your Teltonika RUTX50 could be configured to access the BaseStation network as a client? Alternatively, you could configure the BaseStation Mikrotik to act as a client to the Teltonika, but this is a non-standard configuration and I’m not sure the best settings to use - a LLM AI would provide good advice though, it’s fairly handy with RouterOS devices.
The proxy extension may also be useful - if you access BlueOS via ZeroTier or some other means, you can then access devices on the local ethernet network via it…
