So far we have found 1 issue:
* Sometimes the old/native servers can reach the service, sometimes
they get a timeout
In old calico notes on github it is referenced that overlapping
Pod/CIDR networks might be a problem. Additionally we cannot use
kubeadm to initialise the podsubnet to be a proper subnet of the node
subnet:
```
[00:15] server57.place5:~# kubeadm init --service-cidr 2a0a:e5c0:0:cccc::/108 --pod-network-cidr 2a0a:e5c0::/100
I0829 00:16:38.659341 19400 version.go:255] remote version is much newer: v1.25.0; falling back to: stable-1.24
podSubnet: Invalid value: "2a0a:e5c0::/100": the size of pod subnet with mask 100 is smaller than the size of node subnet with mask 64
To see the stack trace of this error execute with --v=5 or higher
