[Design-team] Firewall Graphics

[Matt Allen]

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 :)
