Protection Against Failover Network Gateway Switching
The network stack of most operating systems is designed to maintain network access at all costs: if the virtual network interface stops responding, browser and system service requests are instantly redirected through the standard gateway. This leads to immediate user deanonymization and session interception without clear on-screen warnings.
How to Configure Reliable Traffic Blocking
- Enable permanent Kill Switch mode in client system settings instead of basic soft mode
- Activate the system option "Block connections without VPN" in Android network settings
- Test the protection by forcibly disconnecting from the server while downloading a test file
- Configure the system firewall to ban outgoing packets through the physical adapter bypassing the tunnel
