What is the major benefit of using NAT with Port Address Translation?
- It allows external hosts access to internal servers.
- It allows many internal hosts to share the same public IPv4 address.
- It improves network performance for real-time protocols.
- It provides a pool of public addresses that can be assigned to internal hosts.
