Hello, how do I verify that flannel is using the Wireguard backend and it's working properly? I added the

HelmChartConfig

as explained here. Restarted the DS, now I want to verify if it actually is using the Wireguard and working as expected. I'm using

v1.32.7+rke2r1

Uses canal for CNI, pretty much all the default installation configs.

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.
