OpenVPN - how to disable internet access after OpenVPN hang

Question

Time to time my OpenVPN connection hang. I want to disable all internet access automatically after VPN hang (to prevent leakage) until I done some "action" or reconnect to VPN.

OS: Windows 7

I am not sure, but currently I have the idea and I am trying to solve this with two .bat files. First, that I must run after connect and second one to reestablish my internet connection without OpenVPN.

At the first .bat I am trying to delete default internet (primary) gateway route delete 0.0.0.0 but the problem is that after disconnection internet works fine and default route automatically reestablish at my route print

Maybe somebody can suggest how to solve this problem? Step-by-step, please.

(sorry for my English, any corrections for my questions are welcome)

Answer 1

A leakage problem is not really a problem for OpenVPN, which has never been designed to allow you to attain perfect privacy. In other words, preventing leakages from OpenVPN is kind of a hopeless task, even if you were to fix the issue you mention.

There are other instruments to do that. In particular, if I were you, I would consider Tor the Onion Router and the whole operating system based on it, Tails. But even more than that, if privacy is of utmost importance to you, I would consider setting up, as a Virtual Machine inside a hypervisor, Whonix, a specifically dedicated Operating System.
