I am using 1 Ubuntu 22.04 and 3 Ubuntu 20.04, ufw is disabled,
- UFW disabled
- Network plugin is Flannel
- net.bridge.bridge-nf-call-iptables=1 is set on all vms.
I can’t perform ping in a pod. I couldn’t get that whether this is a CoreDNS or a Flannel issue. I can provide my configurations if needed but I use default ones right now and doesn’t seem to work for me.
