Does it have a public IP address? Does it provide services towards the
Internet? If so: how can it *not* be a public place?

By your analogy, my lawn becomes a public parking lot because a
driveway connects it to the street.

How about this for an analogy?

You have a fence (firewall),
around your lawn (internal router),
and people walking on the sidewalk (internet),
have to open your swinging gate (open port),
to walk up to your door (service - ie: ftp).

Yes, they are on your property (the lawn/internal router), but if they
want to talk to you, they have to ring the doorbell first and get
permission to come inside.

In order to get you, they have to go through the swinging gate to get
to your doorbell.

So really, all you need is a "no soliciting" sign (ip blocking).
