[hellotiming]

hello,all

once vpn discconnect , the Chrome browser may still request current URL , that may leaks URL with DNS to ISP, so can I have a way to setting it in .ovpn file in openvpn client with some parameter?

What I need is once vpn be disconnected , the internet automatic disconnected (current apdater be disabled) , thank you.

Essentially, you want a "Kill switch" ..

OpenVPN does not have a kill switch but you can probably search the www for one.
