This specifies the NAT boundary at a given router. When configuring Network Address Translation, youвЂ™ll need to specify the INSIDE and OUTSIDE interfaces. This address is allocated from a globally routable address or network space not a private address (RFC1918)

Outside Global - Is an IP address that is assigned to a host on the outside network by the host owner.

Not necessarily a public IP address, it is allocated from an address space routable on the inside.

Outside Local - In an IP address of an outside host as it appears to the inside network.

Inside Global - Is commonly a public IP Address assigned by an Internet Services Provider (ISP) or a Network Operations Center (NOC) that represents one or more inside local IP addresses to the outside world.

This IP Address is most likely to be an RFC1918 private address. This is can be configured statically or obtained via DHCP.

Inside Local - Is an IP address assigned to a host on the inside network.

Inside Global, Inside Local, Outside Global, Outside Local. When dealing with Network Address Translation on a Cisco router youвЂ™ll need to familiarize yourself with four different terms. Now that you have an general understanding of how NAT works, its time to take a look at how NAT operates.

In this case The traffic would originate from 10.17.50.22, go to the router and get translated from 10.17.50.22 to 10.240.18.2 then go to 10.240.18.6 which in turn would be translated from 10.240.18.8 to 10.84.18.7 therefore full IP communication would be functional without any drastic changes to the companies networks. So ABC Inc.вЂ™s server would communicate to 10.240.18.6. Through the magic of Network Address Translation when ABC Inc.вЂ™s server attempts to communicate with XYZ Inc.вЂ™s server they need to use the destination NAT address.

would use 10.240.18.1 on their T1 serial interface and 10.240.18.2 as their NAT address for the source address of 10.17.50.22 and XYZ Inc. In this case there would be six usable host IP Addresses.

agree on using the 10.240.18.0/29 address space for the point to point T1. would need to agree on an IP address allocation used for the connectivity between the two companies. In a scenario like this youвЂ™re in a tough spot but no need to fear, Network Address Translation is here to save the network and possibly your jobвЂ¦Д«oth ABC Inc. In XYZ Inc.вЂ™s network the source address is 10.84.18.7 and the destination needs to be 10.17.50.22 however that address shows up as being located at the corporate head quarters in Dallas, Texas. the source address is 10.17.50.22 and the destination is 10.84.18.7 however the 10.84.18.7 address shows up in ABC Inc.вЂ™s networks routing table as a small branch office in Miami, Florida. In this case Network Address Translation (NAT) would be need to be implemented on both sides of the point-to-point T1. need to establish IP connectivity using a point-to-point T1 and you need to ensure ip communication but both companies use the SAME RFC1918 address space. In which case youвЂ™d need to NAT one to one the source address to a destination address, in this case NAT one to one is commonly performed on both sides.ДЇor example ABC Inc. NAT one to one is commonly used when you go from one autonomous system to another autonomous system and you need your source address when communicating to the destination to be a specific IP address but that IP address does not match your IP address layout. Granted if IPv4 NAT was not created we would have ran out of IP addresses a long time ago but NAT saved us in more ways then one. As more and more address blocks were allocated by IANA, more and more people became worried that we would soon one day run out of IPv4 addresses. NAT was created with the intention to prolong the inevitable which was our ever depleting IPv4 address space. NAT Pooling and Port Address Translation (PAT) will be discussed in the next two labs but for this lab lets dive into the abyss of Network Address Translation (NAT) one to one. Network Address Translation referred to as NAT is used in almost every network in the world in some form or fashion rather it be a NAT one to one translation, NAT pool where a pool of IP addresses are given on a first come first serve basis to the inside private address range or the most famous PAT (Port Address Translation), commonly a misconception and referred to as NAT but PAT translates many inside addresses to a single outside address by using random port numbers for ip communication.
