4.4 NAT
4.4.1 Introduction to NAT
Network Address Translation (NAT) provides a way of translating the IP address in an IP packet header to another
IP address. Originally, NAT is used to allow users using private IP addresses to access public networks. By using of
NAT, a smaller number of public IP addresses can meet public network access requirements for a larger number of
private hosts, thus NAT can effectively alleviate the depletion of IP addresses.
