Cisco IOS Network Address Translation (NAT) and Port Address Translation (PAT) are mechanisms that you can use to conserve registered IP version 4 (IPv4) addresses in large networks, resolve overlapping addressing scenarios, and simplify IPv4 address management tasks. NAT and PAT translate IPv4 addresses within private internal networks to legal IPv4 addresses for transport over public external networks, such as the Internet, without requiring a registered subnet address. Incoming traffic is translated back for delivery within the inside network.
This translation of IPv4 addresses eliminates the need for host renumbering and allows the same IPv4 address range to be used in multiple intranets. This course describes the features that are offered by NAT and PAT and describes how to configure NAT and PAT on Cisco routers.
NAT Configuration, Procedures, and Input Parameters - identify the input parameters necessary to plan the deployment of basic Cisco IOS NAT features Configuring Static NAT and PAT - configure and verify Cisco IOS static NAT and PAT Configuring Dynamic NAT and PAT - configure Cisco IOS dynamic NAT and PAT Troubleshooting Network Address Translation - identify the steps to troubleshoot Cisco IOS NAT operation
