Hi Chris,


Most of my knowledge is second hand so I would advise reading the RFC's on
this (They are actually interesting reading). I have played around with a
few NAT solutions and yes they work, to some peoples definition of the
word  
"work".

If you want to read a well worded and fairly level documentation on
advantages and disadvantages I would advize reading rfc2993 which covers
many different aspects of NAT issues.

I wrote about four paragraphs here but deleted them, I was getting
religious. This happens a lot when NATs are discussed:)

Undeniably people are using NAT's now and they are communicating with
each other and us. NATs have advantages in IP address management, I think 
the question people should ask is "In my specific situation do the
advantages outweigh the disadvantages?". This is a business decision but I
think that most people making the decision aren't even aware of the
issues.

If you get questions give people the link above. Let them make an informed
decision. 

In case you ask, no I don't use NAT, my decision you make yours:)
