Background / Scenario
Network Address Translation (NAT) is the process where a network device, such as a Cisco router, assigns a
public address to host devices inside a private network. The main reason to use NAT is to reduce the number
of public IP addresses that an organization uses because the number of available IPv4 public addresses is
limited.
