When I deploy kube-router with all features (without kube-proxy) and I deploy traefik with hostNetwork=true, the pod can't reach https://10.96.0.1:443/versions with timeouts exception.
What did you expect to happen?
When the pod is deployed with hostNetwork=true, it can reach the Kube API server. This works disabling service proxy in kube-router and enabling kube-proxy, but I want to use only kube-router.
How can we reproduce the behavior you experienced?
Steps to reproduce the behavior:
Step 1
Create a k8s cluster (in my case with k0s)
Step 2
Deploy kube-router with all features
Step 3
Deploy traefik with hostNetwork=true. It can't reach Kube API Service

Additional context
As I can see in iptables, kube-proxy creates KUBE-SERVICES chain, and allows in there 10.96.0.1 in port 443, but kube-proxy hasn't got some similar chain /rule
Thanks in advance

I don't run k0s so it might be a while before I can find time to setup an environment and test it myself.
However, it sounds like kube-router may not be starting, and as such it is not creating the kube-apiserver ClusterIP that traffik needs. I would imagine that this would most likely come about from kube-router not being able to talk to the kube-apiserver.
What happened?
When I deploy kube-router with all features (without kube-proxy) and I deploy traefik with hostNetwork=true, the pod can't reach https://10.96.0.1:443/versions with timeouts exception.
