## Overview

This tiny repository documents Network Address Translation rather than implementing a network service. The README describes the outbound and reply translation flow, the mapping table, and Static NAT, Dynamic NAT, and PAT. No source excerpts were provided, so the graph reflects documented concepts only; hello.html’s contents and behavior are unknown.

Main entry points: [`README.md`](https://github.com/chandu-jannu/nat-explain/blob/main/README.md) (NAT Router)
