Cisco ICND2 1.1: Scaling the Network with NAT and PAT
This course is included in our On-demand training solution.
Two Internet scalability challenges are the depletion of registered IP version 4 (IPv4) address space and scaling in routing. Network Address Translation (NAT) and Port Address Translation (PAT) are mechanisms for conserving registered IPv4 addresses in large networks and simplifying 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 NAT and PAT offer and shows you how to configure NAT and PAT on Cisco routers.
