Explanation
NAT (Network Address Translation) allows a network to use a single public IP address for multiple devices within a private network. It works by modifying the source or destination IP addresses in the packet headers as the traffic passes through a NAT-enabled device, such as a router or firewall. This modification allows multiple devices within the local network, using private IP addresses, to communicate with external networks using a single public IP address. NAT translates the private IP addresses of devices within the internal network to the public IP address when communicating with external networks, and vice versa, enabling the sharing of a single public IP address among multiple devices.
