I have an openVPN client running that seems to be working fine, traffic is routed with encryption to the VPN. Once in a while, this openVPN client fails, or something else in the system fails.
Traffic is then released directly out without encryption and routing and this happens silently. I only notice by checking my final IP address. This is of course horrible that the traffic can without notice bypass all my intended security.
Restarting the openVPN client normally makes the encryption and routing work again.
How can I check what goes wrong?
Preferably, I want the router to refuse any traffic if it does not go through the VPN. How can I do this?
Grateful for all help :-)
