One doesn't. The two scenarios are completely different.

If you're buying 100 workstations, plan to budget for both a perimeter
firewall, and individual protection for each machine. If you can't
get the budget, that might mean you can buy only 95 workstations.
(actually 99 workstations; appropriate one to use as the perimeter
firewall, and the individual protection for the others will be in the form
of tcp_wrappers/xinetd configuration, perhaps with iptables configuration
in addition)

Appropriate configuration for the perimeter firewall and the individual
protection, as I note in an earlier message (and others have noted
previously) is site-specific. You won't be able to get anything that
specific from a newsgroup.

Thanks! Of course, I didn't want to ask for specific settings. I just
wanted opinions on the philosophy and overall structure. Central vs
distributed.
