This preface describes the NAT Administration Guide, how it is organized and its document conventions.

Network Address Translation (NAT) is a StarOS™ in-line service application that runs on Cisco® ASR 5500 and virtualized platforms.

The NAT in-line service translates non-routable private IP address(es) to routable public IP address(es) from a pool of public IP addresses that have been designated for NAT. This enables to conserve on the number of public IP addresses required to communicate with external networks, and ensures security as the IP address scheme for the internal network is masked from external hosts, and each outgoing and incoming packet goes through the translation process.
