Could you build this?

Partial While an Electron or Tauri dashboard is easily vibe-coded, reliable real-time packet/connection monitoring and programmatic IP blocking on Windows requires lower-level OS networking APIs.

What it would actually take: The app needs a native backend service written in C# (.NET) or Rust utilizing Windows Filtering Platform (WFP), ETW (Event Tracing for Windows), or the Win32 Network Management/IP Helper APIs (such as GetExtendedTcpTable) alongside Netsh or WFP rule management. The dashboard communicates via IPC or local REST to this privileged background daemon to enforce timed firewall rules and ingest local MaxMind GeoIP lookups.
