Outside in - one-to-one nat

Internal IP: 192.168.138.152 External IP: 217.198.220.152

Version 8 ASA

access-list H5MAJ2017 permit ip any host 192.168.138.152
access-group H5MAJ2017 in interface OUTSIDE
!
object network OBJ192.168.138.152
 host 192.168.138.152
 nat (INSIDE,OUTSIDE) static 217.198.220.152
!

Version 9 ASA

Ved det ser ud af rigtig meget når man skriver alt det her, men det giver mening i forhold til at holde styr på reglerne i firewallen via det grafiske interface, og det giver nemmere log gennemgang efterfølgende ved evt. fejl.
