aashishdagar007/Firewall ? reverse-engineered prompt

Build me a cross platform C++ firewall app with a live web dashboard.

I want it to watch network traffic, show real time stats, let me view and edit rules, and display alerts for things like suspicious payloads, port scans, and process activity where that is supported. On Linux it should use the system firewall and queue packets so it can actually allow or drop them, and on Windows it should at least work in observer mode with packet logging and process mapping. Please include a built in local web API and dashboard so I can see activity in the browser, manage rules, and inspect recent packets and threats.

Make it feel like a real security tool, with clear logs, safe defaults, and startup checks so it refuses to run if the required network setup is missing. If you need to look up current docs online for any platform specific bits, go ahead.
