Gateway mode
The more ambitious path, with the most careful caveats
Gateway mode is where IoTSentinel becomes more than a visibility project. It is also the part that needs the most honesty, because once the Pi sits in the traffic path, mistakes have real network consequences.
What gateway mode is
Gateway mode routes device traffic through the Pi so the project can move from light visibility into deeper inspection, anomaly signals, and inline response paths.
Why it matters
This is the path that unlocks the strongest differentiators: real-time anomaly work, richer investigations, and more meaningful IDS/IPS behavior beyond passive observation.
Why the framing is careful
Routing traffic is a higher-stakes feature than showing a dashboard. That means setup safety, lockout avoidance, hardware variance, and documentation all matter more here.
Current status
The project already contains important gateway-oriented building blocks, but this path is still being hardened and documented. It is a roadmap-forward capability, not the part of the project to oversell.
