I agree with Andrew's reasons for using LEAF.  It has been my perimeter
firewall for many years.  However, by far, my preferred network
architecture involves a perimeter firewall as a "standalone" box that
does only that "first line of defense" job.  I put some value on being
able to Power-Cycle my perimeter firewall without overly disturbing the
internal network.  IMHO, that simplicity makes for more robust security.
If I can't do the job that way, it makes me re-analyze my plan and see
what I want to do "wrong".  "Fancy" things, like poking holes through a
perimeter firewall, may not always be wrong, but they certainly suggest
a different architecture should be examined.  Putting any sort of
"development tools" on a perimeter firewall is always wrong, IMNSHO.  So
far, so good, but, yes, I concede there are more complex architectures
that might be relevant in advanced cases.

I know many places regularly junk old hardware, and being forced to use
newer stuff can lead to the sort of hardware support problems Andrew has
had. Personally, I put a value on the sort of simplicity to be found in
the old hardware. "Uncomplicated" is a good thing.  The requirement I
have for saving an old box that can be "repurposed" to, say, a LEAF
perimeter firewall is reliability, "it just works".  At this point in
time, a suitable old box can still be found if one looks for it.  And in
at least one case, I've donated an old classic Pentium box to the cause.

It is behind my perimeter firewall where I accept a bit more complexity.
For example, this workstation's iptables has something like 140 rules,
more or less--it's very strict.

One day my position may become untenable, but not yet I think.  Until
then I'll prefer the tried and true.  IMHO, if my LEAF perimeter
firewall still presents a strong, "impenetrable" first line of defense
sitting there alone, it's just fine as it is.
