point taken. normally, i put a fair bit of packet filtering in the router
between the DMZ and the internet, and clamp down tight on the (unix based)
hosts in the DMZ, so the motivation to go to the three legged design isn't
as great. folks who are stuck with M$ product in the DMZ may not be able to
clamp down adequately.
baring any technical mistakes in my document, i'll probably put a note in
about the three legged design having some advantages, and promise a follow
up version of the document at a later date which includes such a design.
my principal goal in this document was to show the pf and nat rules and
how they interact, and not to provide a best-of-breed design.
