System Documentation

What problem does it solve?

Diagnoses and fixes conflicts that prevent Tailscale from coexisting with proxy/VPN tools on macOS, covering five conflict layers including route hijacking, HTTP proxy environment variables, system proxy bypass, SSH ProxyCommand double tunneling, and VM/container proxy propagation.

Core Features & Use Cases

  • Diagnostic workflow for common conflict scenarios across macOS when Tailscale traffic is misrouted.
  • Prescribed fixes for route hijack, proxy envs, system proxy bypass, and SSH/git proxy pitfalls to restore reliable connectivity.
  • Real-world use cases include SSH access to remote Macs, Git operations through proxies, and Docker/VM networking with Shadowrocket/Clash/Surge active.
  • Example: diagnose why browser shows 503 while curl succeeds and apply a DIRECT rule + NO_PROXY tweaks.

Quick Start

Run the Tunnel Doctor quick diagnose to identify the active proxy conflict layer and apply the recommended fixes.
