hi everyone, i'm an amateur with limited knowledge about network configuration, trying to build a network on a sailboat.

there will be 2 WAN providers:

primary: 1 4G LTE modem-router (cheaper connection, with higher data plan, accessible while in port and close to the shore)

seccondary: Starlink global (expensive connection, with limited data plan, to be used once vsl is far from shore and mobile antennas).

Then to distribute the service via 2-3 access points (lan wired) for connectivity in most areas of the ship.

So, the plan is to configure a failover (not sure if the best option is to set a ping time, reduced bandwith or what option do you recommend?

And also, would like an "auto-recovery" to the 4G internet provider, once the boat is returning to shore, and picks up signal. This would be crytical to avoid unnecessary use of the starlink once the 4g is back operative.

Do you know if this is possible, and how to configure it?

Thanks!
