## What it is
NSmartProxy is an open-source NAT traversal / reverse proxy tool that creates secure tunnels from a public endpoint to services running behind a firewall or NAT. It consists of a server component deployed on a public host and a client component deployed on the intranet, built fully asynchronously on .NET Core.

## Use cases
- expose a local web server to the internet behind NAT
- remote desktop into a home computer from outside
- port forward FTP, SSH, or RDP through a firewall
- access intranet services without a public IP
- tunnel TCP and UDP services through a public relay server
- self-host a reverse proxy tunnel server

## When to choose
- you need to expose internal TCP/UDP services to the public internet
- you want a cross-platform (Windows/Linux/macOS/Docker) tunneling solution
- you need to map multiple LAN services through a single client
- you prefer a free, self-hosted alternative to ngrok

## When to avoid
- you only need HTTP-level load balancing rather than NAT traversal
- you require a managed cloud tunnel service with no server setup
- your environment lacks .NET Core or Docker and you need a single static binary
- you need enterprise-grade support or extensive documentation
