This definitely helps explain your misconceptions about NAT as a =
security tool.
Globally addressable !=3D globally reachable.
Things can have global addresses without having global reachability. =
There are
these tools called access control lists and routing policies. Perhaps =
you've heard
of them. They can be quite useful.
