[Warning, operational content.] Remember that most "firewalls" or other "middleboxes" on the Internet are completely unmanaged. They were configured once and for all. (See the problems with former bogons or with 192.0.0.0/8.) The architecture of the Internet was designed for a network where all the routers were heavily managed and by knowledgeable people.
