## What it is
lanproxy is a self-hosted NAT traversal / reverse proxy tool that exposes machines behind a firewall to the public internet by forwarding TCP traffic through a public server. It supports any TCP-based protocol (HTTP, HTTPS, SSH, remote desktop, SOCKS5) and includes a web-based admin panel with multi-client support.

## Use cases
- expose a local web server to the public internet
- access my home computer from outside the network
- debug local payment callback interfaces from the web
- ssh into a machine behind NAT
- remote desktop into an office PC from home
- self-hosted alternative to ngrok or frp
- tunnel internal services through a public VPS

## When to choose
- you want a free, self-hosted ngrok/花生壳 alternative with full control over your data
- you need to forward arbitrary TCP protocols, not just HTTP
- you have your own public server and want multi-client tunnel management with a web UI

## When to avoid
- you only need HTTP tunneling with zero setup and are fine with a hosted service
- you need UDP forwarding - lanproxy only handles TCP
- you require a commercially licensed product - the repo has no explicit license
