Gooserelayvpn Socks5 Tunnel

aradotso/trending-skills

This skill teaches Claude how to set up GooseRelayVPN, a SOCKS5 proxy that tunnels TCP through Google Apps Script to your own VPS. The setup uses domain fronting (SNI shows www.google.com while talking to script.google.com) and end-to-end AES-256-GCM encryption, so Google never sees your plaintext traffic. You'd use this when you need to bypass restrictive firewalls or route traffic through Google's infrastructure without giving them the decryption keys. It covers the full stack: building or downloading the Go binaries, deploying the tiny Apps Script forwarder, configuring both client and server with matching tunnel keys, and scaling across multiple deployments when you hit the 20k daily call limit. The architecture is clever but requires maintaining your own VPS exit node.

GooseRelayVPN SOCKS5 Tunnel Skill

What It Does

GooseRelayVPN is a SOCKS5 proxy that tunnels raw TCP through a Google Apps Script web app to a self-hosted VPS exit server. The traffic path:

Browser/App
  -> SOCKS5 (127.0.0.1:1080)
  -> AES-256-GCM encrypted frames
  -> HTTPS to Google edge IP (SNI=www.google.com, Host=script.google.com)
  -> Apps Script doPost() — dumb forwarder, never sees plaintext
  -> Your VPS :8443/tunnel — decrypts, dials real target
  <- Same path in reverse via long-polling

Key properties:

  • Domain fronting: TLS SNI shows www.google.com; actual host is script.google.com
  • End-to-end AES-256-GCM: Google never holds the key
  • Raw TCP tunneling: SSH, IMAP, custom protocols — anything SOCKS5 carries
  • Multi-deployment load balancing: Round-robin + health-aware blacklist across multiple Apps Script deployments
