I've asked the same thing, and it seems the logical thing to return.

I would think that if a PM has 30 IP's in it's assigned pool, it should
return no route when one of those IP's is not in use. It's current
behavior of passing it to it's own gateway router is weird and only
makes sense for things in the assigned pool (it's valid behavior for
IP's assigned via RADIUS, say, like static IP's for some customers).

And, no, it's not just you.
