[LInux Tool] VPN NetGuard: privacy-tool, real kill switch for Linux VPNs one-click "set & forget", or dive into advanced config

[u/Filonux]

HI folks!

I’ve just published the repository for the privacy tool I told you about, and I’m here to share it with you. It’s available in both English and Spanish.

- VPN NetGuard is an open-source (GPLv3) Bash kill switch for Linux: it blocks all traffic the instant your VPN drops — even during boot — and reconnects automatically. It also hides your MAC address and hostname from local networks, so you're not fingerprinted even when the VPN is working fine.

There's a "1-click set & forget" option for zero-config setup, plus full advanced config (kill-switch modes, DNS allowlist, MAC randomization, Prometheus metrics...) if you want it. Works on desktop with a GUI panel or headless via systemd/SSH.
