On a related issue, yesterday I discovered a number of sites that
claimed to have a firewall in place with RFC 1918 space on one side
and Internet space on the other. on investigation, it turned out
that the firwall was a router, routing the RFC 1918 space and consisted of
specific ACLs for services.
I came away impressed.
