TunMon
TunMon runs your tunnel itself and tells you, in plain English, whether your traffic is protected. It imports your server from v2rayN on first launch, runs the xray and sing-box engines directly, recovers from drops on its own, and asks before updating itself.
Before you install
- Windows 10 or 11.
- v2rayN installed with a working server. TunMon uses the engines that come with it and imports your server; v2rayN itself doesn't need to be running.
- The .NET 10 Desktop Runtime. If it's missing, Windows offers it when TunMon first starts.
- Windows may say it protected your PC, because TunMon isn't from the Microsoft Store. Choose More info, then Run anyway.
What's new in 1.0.5
TunMon is more honest about your connection: it only shows Protected once it has confirmed your traffic leaves through your VPS, and says it's checking otherwise. The connection TunMon uses for traffic stats is now password-protected. New: Export report for sharing saves a report with your addresses, Wi-Fi names and user name removed. TunMon now shows exactly which programs it would close, and leaves proxy settings alone if they point somewhere else.
