In the

kube-flannel

logs I can see in the control plane node:

Found network config - Backend type: wireguard

Same container in a worker node outputs this:

Found network config - Backend type: vxlan

Do I need to do configurations in the worker nodes too? or just the server node?

Using

tcpdump

I can see that only the

vxlan

port is being used and not the wireguard port.
