# SNI-routing deployment: HAProxy (443) -> mtg + real web backend
#
# This setup puts an SNI-aware TCP router in front of mtg so that:
#   - Telegram clients (FakeTLS with the correct SNI) are routed to mtg
#   - All other TLS traffic (including DPI probes) reaches the real web
#     server, which responds with a genuine certificate
#
# The result: active probes see a real website; passive DPI sees matching
# SNI/IP because the domain resolves to this server's IP.
#
# Quick start:
#   1. Set YOUR_DOMAIN below (and in mtg-config.toml)
#   2. docker compose up -d
#   3. mtg generate-secret YOUR_DOMAIN   -> put it in mtg-config.toml
#   4. docker compose restart mtg
#
# See BEST_PRACTICES.md and the project wiki for background.
