Hi Pete,
Unfortunately I'm a bit swomped at the moment (might have some time in
the future if you're still in need), so can't help out with the graphics
themselves right now, although thought I'd throw a view on your analogy
your way.
The Post Office idea is good, however personally I'd see the firewall as
more of the post office distribution (or sorting) centre. Anyone can
send you mail, which ends up at a distribution centre, this centre
filters your mail, deciding what gets passed through to your address,
returned to sender or forwarded elsewhere (based on your personal rules
for allowed 'mail'). The postman then arrives at your house with all
mail the distribution centre has allowed through and delivers the mail
which matches the mailboxes on your door which are open ('listening'),
all other mail without open services (or open letter boxes for this
analogy) are rejected.
In this analogy I realise that everyone would have 65,535 plus potential
ports on their door, but in the graphics you would label each letterbox
with a port number and only show open (listening) letterboxes on the
door, which all mail has labelled with your address (your IP address).
So the address on the envolope would be:
Mr P Sherman
127.0.0.1:42
The IP representing your address on an envelope, the port representing
the letterbox on your door.
Ping me a message if this doesn't make sense or if you want to run
through anything else :)

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