Key Scripts

VPN Kill Switch (vpn/wg-safe/)

A secure WireGuard VPN manager with built-in kill switch functionality to prevent IP leaks when VPN connections drop unexpectedly.

Features:

• Kill Switch Protection: Automatically blocks all internet traffic when VPN connection is lost
• IPv6 Leak Prevention: Disables IPv6 during VPN connection to prevent leaks
• Connection Monitoring: Continuously monitors VPN status and maintains firewall rules
• Emergency Recovery: Manual firewall restore function

Usage:

sudo vpn/wg-safe/main.sh up <profile>      # Connect with kill switch
sudo vpn/wg-safe/main.sh monitor <profile> # Monitor connection status
sudo vpn/wg-safe/main.sh down <profile>    # Disconnect safely
sudo vpn/wg-safe/main.sh restore-firewall  # Emergency restore

See vpn/wg-safe/README.md for detailed documentation.
