To prevent what "from being taken over by a botnet/hacker"?  If they
break into my boat and have access to the computer there then there's
absolutely nothing that using a VPN will prevent.  As I've said it has
to be capable of restarting with the connection in place without my
interaction.  A VPN doesn't help in the slightest as far as I can see.

Exactly the problem, I don't need this at all.  I want communication
in the other direction only.

Getting back to my original requirement:-

    I want to communicate *from* my home system to a headless SBC.

    The headless SBC (Pi or whatever) can connect to the internet but
    it's almost certainly going to be behind a NAT/firewall of some
    sort.
