TunnelForge

Developers operating behind NATs, firewalls, or dynamic edge networks often struggle to expose local services without complex router changes or centralized third-party relays. TunnelForge solves this challenge by establishing an authenticated, bidirectional TCP reverse tunnel between an internet-facing edge server and local client applications. ## Key features - **Timing-safe token authentication:** Employs HMAC SHA-256 verification to authenticate incoming control plane sessions against secret tokens securely. - **Multiplexed data streaming:** Provisions on-demand TCP channels dynamically, bridging incoming public socket traffic directly to local target ports with 64 KB buffers. - **Built-in economic metering:** Tracks byte counts, active connections, uptime, and calculates accrued operational bandwidth costs per megabyte in real time. - **Heartbeat status exchange:** Maintains persistent control sessions and responds to metric ping requests with comprehensive telemetry snapshots. ## Example ```bash python tunnelforge.py --help python tunnelforge.py server --token 8f3c7e2b1a90d45681234cde5678ef01ab34cd56ef7890ab python tunnelforge.py client --token 8f3c7e2b1a90d45681234cde5678ef01ab34cd56ef7890ab ``` ## Limitations TunnelForge operates strictly at the raw TCP level and does not provide TLS encryption, HTTP header inspection, or automatic domain routing.
