Well, actually, the purpose is to *protect* what's behind it, which
doesn't necessarily mean conceal it.  Steve Gibson seems to think the two
are inseparable, but I don't necessarily agree.  In any case, the point of
the DMZ is to have some servers which you *intend* to have accessible to
the outside, so "concealing" them is rather pointless.
