Prevent VPN Start-up IP Leak - Windows - Manual Kill Switch

[wideopen]

Most VPN providers have given an option to disable IPv6 and an option of a built in Kill Switch. You might already know what they mean. But on many occasions they fail or somehow leak your IP. Below is a simple yet an effective way to block such issue.

 

Do not enable "Auto-Connect" to Wi-Fi. This is the biggest issue. Users will get connected to a local network as soon the PC boots. Solution is to connect manually at each boot. Windows will still remember the Wi-Fi credentials so this is a one-click connect. Most critical step is to disconnect before powering off the machine to be safe. Many BIOS too have option to disable Wi-Fi as needed if you forget the steps here.

 

Ethernet is even more easier as the authentication is done without having to rely on Windows. All you have to do is disable it after a power off and re-enable it after turning on machine. Once you memorize these steps, if anything goes wrong, you can always go paranoid and pull the plug of the Ethernet and stay further protected. Remember, that Ethernet will get reconnected after a connection drop, but this won't leak your IP.

 

Now, feel free to connect to a VPN with its Kill Switch always on. Also, in any case your connection drops, the network will remain disconnected and will require your input to get connected to a Wi-Fi.
