## What it is
Dog Tunnel is a Go-based peer-to-peer tunneling tool that provides port mapping over UDP using the KCP protocol, with NAT hole punching assisted by a rendezvous server. It also supports SOCKS5 proxying and includes a server component (dtunnel_s) with remote admin APIs and optional MySQL-backed user management.

## Use cases
- expose a service behind NAT via p2p port mapping
- tunnel traffic between two machines without a public IP
- run a socks5 proxy over a kcp-based p2p tunnel
- bypass restrictive NATs with udp hole punching
- self-host a tunnel server with user accounts and traffic limits
- forward remote ports to local machine over udp

## When to choose
- you need p2p port forwarding with NAT traversal over UDP/KCP
- you want a self-hosted tunnel server with multi-user management
- you need a lightweight Go tool with socks5 proxy support

## When to avoid
- you need a maintained tool - the repo was archived in 2024 and the official server is gone
- you need TCP-based tunneling or modern TLS features
- you want an actively supported community or documentation
