Static NAT creates a permanent, one-to-one mapping between an address on an internal network and a perimeter or
external network. To share a Web server on a perimeter interface with the Internet, use static address translation to map
the actual address to a registered IP address. Static address translation hides the actual address of the server from users
on insecure interfaces. Casual access by unauthorized users becomes much more difficult. Static NAT requires a dedicated
address on the outside network for each host.

Define a range of IP addresses that are hidden from the public Internet. NAT modifies network
address information in the defined IP range while in transit across a traffic routing device. NAT
only provides IP address translation and does not provide a firewall. A branch deployment with
NAT by itself will not block traffic from being potentially routed through a NAT device.
Consequently, NAT should be deployed with a stateful firewall.
