Detailed explanation-1: -A Network Address Translation (NAT) is the process of mapping an internet protocol (IP) address to another by changing the header of IP packets while in transit via a router. This helps to improve security and decrease the number of IP addresses an organization needs.
Detailed explanation-2: -NAT Security Because NAT transfers packets of data from public to private addresses, it also prevents anything else from accessing the private device. The router sorts the data to ensure everything goes to the right place, making it more difficult for unwanted data to get by.
Detailed explanation-3: -Static (map) network address translation (NAT) provides a one-to-one mapping of private IP addresses to public IP addresses. It allows you to map an IP address on your internal network to an IP address that you want to make public.
Detailed explanation-4: -Dynamic NAT Configuration. The default dynamic NAT configuration automatically applies dynamic NAT to all traffic from one of the three private IP address ranges to any external interface.
