In this episode you will learn:

- Static NAT creates a permanent one-to-one mapping, ideal for hosting internal servers like web or email servers.

- Dynamic NAT maps private IPs to a pool of public IPs, but connections fail if the public IP pool is exhausted.

- PAT (Port Address Translation), or NAT Overload, allows many internal devices to share a single public IP address by using unique port numbers to track sessions.

- Understand the four NAT address types: Inside Local (private source), Inside Global (public source), Outside Global (public destination), and Outside Local (destination as seen by the internal network).

- Use the `show ip nat translations` command to view active NAT mappings and troubleshoot connectivity issues on the CCNA exam.
