1.3.1. IP forward
リンクのコピーリンクがクリップボードにコピーされました!
You must use ip_forward to access network connectivity.
The host network sysctl net.ipv4.ip_forward kernel parameter is automatically enabled by the ovnkube-master container when started. This is required to forward incoming traffic to the CNI. For example, accessing the NodePort service from outside of a node fails if ip_forward is disabled.
