VPS Proxy Tunnel

Set up an HTTP proxy tunnel through a remote VPS to bypass network restrictions. Pattern: local server → SSH tunnel → VPS running tinyproxy → internet.

When to use

• Your server is behind a national firewall (e.g., China mainland) and needs to reach GitHub, Finnhub, SEC EDGAR, OpenAI API, etc.
• You have a VPS in a jurisdiction with open internet (Silicon Valley, Singapore, Japan)
• The VPS has SSH access (key-based auth only, password disabled)
