  • Static Network Address Translation (NAT) creates a permanent, one-to-one mapping between an address on an internal network (a higher security level interface) and a perimeter or external network (lower security level interface). For example, to share a web server on a perimeter interface with users on the public Internet, use static address translation to map the server’s actual address to a registered IP address. Static address translation hides the actual address of the server from users on the less secure interface, making casual access by unauthorized users less likely.
