This is a very interesting article:

I'll forgive the guy for thinking of high speed packet filters as the
only type of "firewall" and some other conceptual blubobs. We can also
ignore the title, since there are still firewalls segmenting different
security perimeters, which is the thrust of the current article series
on the www.isaserver.org Web site, and two more article series showing
some other ways to do network security perimeter segmentation using ISA
firewalls.
What's interesting is that only the servers and other core network
assets are protected and only to and from these assets are strong
network access controls enforce. All the clients are considered
untrusted, and sit behind an Internet router that lets everything in and
out. I suppose this guy has a lot of public addresses to get away with
this, but some companys have hundreds and thousands and tens of
thousands to throw around.
I'm going to chew on this idea some more, and see if I can tell a good
ISA firewall story around it. It certainly would solve the "Open Port"
button issue.
