Is there any configuration or package that can kills the internet connection to the devices served by the VPN tunnel when the VPN is down?
For some reason I experience DNS leak when connecting to some locations via OpenVPN. How can I plug the leak.
I'm using a WRT1200AC router and ExpressVPN for privacy.
@dbischof90 - The router, by definition, must always have access to the internet, or else it would not be able to contact the VPN server to establish the tunnel in the first place. You might be able to construct firewall rules to limit outgoing traffic -- only allowing certain destination hosts, for example -- but it might end up causing lots of headaches.
