## What it is
Pingtunnel is a Go-based tool that tunnels TCP and UDP traffic over ICMP echo packets, with a client-server architecture and SOCKS5 forwarding support. It runs on Linux, Windows, and macOS, and is also available as a Docker image and community Android client.

## Use cases
- tunnel TCP traffic over ICMP to bypass firewalls
- forward UDP traffic through a ping tunnel
- set up a SOCKS5 proxy over ICMP
- circumvent networks that block TCP/UDP but allow ping
- run a tunnel server in Docker on a public VPS

## When to choose
- your network blocks TCP/UDP but allows ICMP echo
- you need a lightweight self-hosted tunnel with SOCKS5 support
- you want a single-binary cross-platform tunneling tool

## When to avoid
- you need general-purpose VPN with full OS-level traffic routing
- ICMP is filtered or rate-limited by your network
- you require encryption guarantees beyond the tool's key-based protection

## Facets
- artifact type: cli-tool
