NAT purpose and usage?

Network Address Translation (NAT) plays a crucial role in modern networking, much like a Palo Alto Firewall Course enhances your understanding of network security. NAT primarily serves two key purposes: conserving IP addresses and enhancing network security.
In the realm of "Palo Alto Firewall Training," NAT conserves public IP addresses by allowing multiple devices within a private network to share a single public IP address. This optimization ensures efficient use of available IP addresses, especially in scenarios where IPv4 addresses are scarce.
Moreover, NAT strengthens network security by acting as a barrier between the internal network and the external internet.
