This chapter showed you the basics of address translation: its components, how it works, and how to configure it. Many uses of address translation, and many different types, exist. In the most common case, address translation is used to translate private addresses to public addresses as traffic leaves a network, destined for a public network, such as the Internet. Normally, dynamic NAT and PAT are used to handle outbound connections; static NAT and PAR are used to handle inbound connections. As with any solution, address translation provides benefits and has limitations.
Next up is Chapter 12, which shows you some of the issues with address translation and how the Cisco IOS can deal with these issues.
