(based on your personal rules for allowed 'mail'). The postman
then arrives at your house with all mail the distribution centre

<blockquote type="cite">Hello,<br>
<br>
The Fedora Docs team is planning on writing a Firewall Guide, to
explain<br>
what a firewall does, how it functions, and how to administer it.
For<br>
the initial explanation, I think that some visuals would be very
helpful<br>
to the reader.<br>
<br>
Right now, the best allegory I can contrive is a post office. The<br>
outside network is.. well, anyone who might send mail. The
postman is<br>
the firewall, the post office boxes are ports, and the customers
who get<br>
mail in the boxes are listening services.<br>
<br>
Is there anyone on the design team that would like to hammer the
idea<br>
into something useful, and work with us on creating imagery for
this guide?<br>

Hey Matt,<br>
<br>
Your analogy is close to the same. Instead of PO Boxes, there are
letterboxes; you have a distribution center in place of the local
post office staff doing the sorting. Having spent some time
observing in such places, I think your view has the potential to be
more appropriate as the discussion progresses. I do worry that
detailed comparisons to logistical organizations could grow to be
just as esoteric to the layman - but that's where the graphics come
in :)<br>
<br>
We probably won't start on this in earnest until after the F21
release, but I find that some time with the idea rattling around in
my head helps. Feel free to jump in as much as you like, the
content will live at
