Which is why Jay said "closure" - that means (basically) "across *all*
meaningful right hand sides, plus nay *new* ones that pop up as previously
undiscovered left hand sides along the way.

And yes, this definition *does* mean that if you find a reachable webserver
in a corporate DMZ, and that webserver can reach machines that are behind the
corporate firewall, those supposedly firewalled machines are "on the internet"
as well.

Which is what your security geek was trying to explain to you :)
