title: OpenVPN stops working after Calico enabled (networkpolicy for nodes option in GKE)
body: <p>I've enabled networkpolicy for nodes to manage traffic inside my cluster and noticed, that OpenVPN stops working after I applied this option, other things works fine, same as if I login to openvpn pod and try to access external network, applying networkpolicy doesn't help, how can I fix and why did it happen?</p>
