## What it is
Fuso is a lightweight, fast, cross-platform intranet penetration (NAT traversal) and port forwarding tool written in Rust. It supports multiple connections, cascading proxies, SOCKS5 proxying, UDP forwarding, and encrypted transmission.

## Use cases
- expose a local web server behind NAT to the internet
- forward traffic to an internal RDP port like 10.10.10.4:3389
- set up a SOCKS5 proxy with UDP forwarding and password auth
- chain multiple clients in a cascading bridge topology
- get notified on Telegram when clients connect or disconnect
- tunnel through restrictive networks with KCP transport

## When to choose
- you need a small, fast, self-hosted alternative to frp or ngrok
- you want port forwarding plus SOCKS5 and cascading proxy in one binary
- you need cross-platform NAT traversal with encrypted transport

## When to avoid
- you need a web management panel or webhook features, which are not yet implemented
- you need UDP forwarding in bridge mode, which is unsupported
- you need extensive documentation or enterprise support

## Facets
- artifact type: cli-tool
- maturity: active
- function: proxy, networking, security
- domain: networking, self-hosted, privacy
- platform: windows, cross-platform, cli
- tags: nat-traversal, port-forwarding, tunnel, socks5, kcp, udp-forwarding, cascading-proxy, encryption, linux, macos
