NetCtrl v2.1.4 - Windows Kernel Routing Suppression & Complete Block

What's Changed in v2.1.4

• Suppressed Windows Kernel IPv4 Forwarding:
  • Automatically disables Windows TCP/IP interface forwarding (netsh interface ipv4 set interface <name> forwarding=disabled and PowerShell Set-NetIPInterface -Forwarding Disabled) and sets IPEnableRouter = 0 on application launch.
  • Previously, if Windows IP routing was enabled in the OS registry (e.g. from legacy SelfishNet tools), the Windows kernel routed packets at the IP stack level independently of user-space packet dropping, causing blocked devices to still reach the internet. With kernel forwarding suppressed, NetCtrl maintains 100% exclusive Layer-2 drop and rate-limiting authority.

NetCtrl v2.1.3 - Fix Dashboard WebView CORS & Engine Connection

What's Changed in v2.1.3

• Resolved Dashboard "Engine Reconnecting" Lock:
  • Fixed Rust engine (server.rs) and Python server (server.py) CORS layers. Previously, allow_origin was strictly locked to "null", which blocked PyWebView requests originating from http://127.0.0.1:<port>.
  • Added dynamic loopback origin reflection (http://127.0.0.1:*, http://localhost:*, null, https://pywebview.api, https://appassets.html), allowing Edge WebView2 to communicate seamlessly with the local REST API while strictly rejecting external domains.
• Resilient API Token Loading:
  • web/app.js now handles immediate availability, event listeners, interval polling, and graceful timeout so token initialization can never deadlock.

NetCtrl v2.1.2 - Installer Bugfix & Clean Self-Uninstaller

What's Changed in v2.1.2

• Fixed Installer Runtime Crash: Resolved NameError: name 'time' is not defined in installer_gui.py during process cleanup.
• Automated Self-Deleting Uninstaller:
  • uninstall.bat automatically self-elevates if needed.
  • Gracefully terminates any running NetCtrl processes.
  • Cleans up Desktop and Start Menu shortcuts across all user and public profiles.
  • Automatically deletes the entire installation directory (C:\Program Files\NetCtrl) in the background without requiring manual folder deletion.
• Windows Apps & Features Integration: NetCtrl Pro now properly registers in Windows "Installed Apps" / Control Panel with full uninstall support.

NetCtrl v2.1.1 - Engine Lifecycle & Socket Collision Fix

What's Changed

• Resolve Port 8765 Socket Collision: Added automatic detection and termination of stale background engine processes on startup, ensuring the local REST API always binds cleanly.
• Windows Job Object Lifecycle Binding: Engine process is now tied directly to the OS Job Object (JOB_OBJECT_LIMIT_KILL_ON_JOB_CLOSE), guaranteeing immediate termination when the GUI exits.
• Engine Watchdog: Engine monitors parent PID heartbeat (--parent-pid) and exits cleanly if the parent process terminates.
• TcpListener Retry Loop: Server retries binding up to 10 times with backoff if the port is temporarily held by a closing socket.
• Installer Process Lock Resolution: Setup wizard now gracefully terminates any running NetCtrl processes before file extraction, preventing Permission Denied file locks in Program Files.

NetCtrl v2.1.0 - Secured Local API & Performance Release

What's Changed

• Secure REST API: Per-launch random 32-character Bearer token authentication required on all endpoints in both Python & Rust engines.
• CORS Isolation: Restricted cross-origin access strictly to the local PyWebView origin (null).
• High-Performance Lock-Free L2 Forwarding: Full packet capture and forwarding engine in Rust with pre-cached MAC tables and Npcap optimization.
• Unicast ARP Restoration: Clean network un-spoofing ensuring target devices seamlessly restore direct gateway communication on shutdown.
• Automated Silent Installer: Setup wizard automatically installs WinPcap-compatible Npcap driver and sets up desktop & start menu shortcuts.
