📄 Description

Describe your changes

Add an explicit public port for the proxy main listener and route TLS passthrough mappings on that external port through the existing main SNI router. This handles ingress port translation such as public 443 to internal 8443 without breaking HTTP services sharing the listener.

Custom TLS ports continue to create dedicated listeners. The generated self-hosted configuration now declares the public port explicitly.

Summary by CodeRabbit

New Features
- Added support for configuring the proxy’s externally visible HTTPS port.
- Introduced a --public-port CLI option and NB_PROXY_PUBLIC_PORT environment variable (default: 443).
- Updated the reverse proxy to route traffic arriving on the configured public port using the primary routing path for consistent SNI-based behavior.
Bug Fixes
- Fixed handling where the public HTTPS port could be treated like a separate custom port, avoiding incorrect per-port router behavior.
