MTG - MTProto proxy for Telegram

MTG is a highly-opinionated, standalone MTProto proxy for Telegram. It provides a fast, lightweight proxy that helps bypass network restrictions by using domain fronting.

Features

• Domain fronting: Auto-generates a secret tied to a real HTTPS domain (e.g. google.com), making the traffic look like normal HTTPS
• Automatic IP blocklists: Downloads and applies FireHOL-based blocklists to filter malicious traffic
• Anti-replay protection: Prevents replay attacks via built-in caching
• Prometheus metrics: Optional /metrics endpoint for monitoring
• Minimal footprint: Single binary, no runtime dependencies

How it works

Once installed, the proxy runs on the chosen port. Users connect from Telegram using the generated secret. Traffic is tunneled through an HTTPS-looking connection to Telegram's data centers, bypassing deep-packet inspection.
