static (inside,dmz) x.x.x.x x.x.x.x


the above is called self static which means whenever source behind inside x.x.x.x goes to dmz it will remain unnatted, this is as good as nat 0 acl

Hi ..


Basically this is commonly used for allowing access to the REAL IP addresses of your inside devices from a lower security level interface (i.e DMZ) . You need this type of configuration when traffic is initiated from lower to higher interface and you need to connect to the REAL IP address of the destination hosts .. if you don't configure this static you will not be able to connect to the real IP addresses of the hosts behind the lower interface.
