Far too many "security" folks are dictating actual implementation details
and that's fundamentally wrong.
A security policy should read "no external access to the network" and it
should be up to the network/firewall folks to determine how best to make
that happen. Unfortunately many security policies go so far as to
explicitly require NAT.
