How to let somebody else reach a loopback node.
A loopback node is not reachable from another machine, and that is
invariant 9 doing its job rather than a limitation to route around.
Both answers here keep it that way: an ssh tunnel and tailscale serve each terminate somewhere else and forward to 127.0.0.1, so
the node never binds an address the internet can see.
