There are other benefits of using NAT as well. Network topology outside the local domain can change in many ways. Customers may change providers, company backbones may be reorganized, or providers may merge or split.

Whenever the external topology changes, address assignments for hosts within the local domain must also change to reflect these external changes. Changes of this type can be hidden from users within the domain by centralizing changes to a single address translation router. NAT enables access for local hosts to the public Internet and protects them from direct access from the outside. Organizations with a network setup predominantly for internal use, with a need for occasional external access are good candidates for this scheme.

A NAT-enabled router is installed between the public network and the private network. The role of the NAT-enabled router is to translate between the internal private IPv4 addresses and the assigned public IPv4 address, so all the devices on the private network are able to share the same public IPv4 address. These global addresses are available to assign to hosts on its private network either statically or dynamically. Connections across the NAT boundary are typically initiated by hosts on the private network sending outbound packets to an external host.

These hosts are usually assigned dynamic temporary IP addresses for this purpose. NAT will typically assign these local hosts a static permanent IP address:port. A NAT-enabled router typically has two network interfaces. One interface is connected to the public Internet; the other is connected to the private network.

Step 5. Note: The range length must not exceed the number of valid IP addresses. For this example, 7 is used. Step 6. Step 7. From the Interfaces drop-down list, choose a source or port to map the static NAT. Network address translation. Nat presentation. Network address translation pdf. Ip address.
