I'm a little confused with most of the documentation I found on the Cisco website. In some documentation, they should if you are going from inside to dmz, then use
Static (inside, dmz) 172.18.1.0 172.18.1.0 netmask 255.255.255.0
In other docs, use NAT (inside) 0.
What one leads itself to a better overall configuration if you have requirements for multiple DMZ areas with security requirements for each.
