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?

just enabling running calico pods should not cause any connectivity issues with your current pods. Can you make sure there are no network policies currently running in the cluster? – Patrick W Feb 26 '19 at 19:30

2@PatrickW https://serverfault.com/questions/955785/connects-to-openvpn-but-no-access-to-local-network-or-internet-in-kubernetes-gke I've recreated here, Calico core dev said that Calico might block connection because of ip spoofing and seems unsecure, but I didnt validate it yet – animekun Feb 27 '19 at 13:54
