I found that if a namespace is put into a Project, Rancher will automatically create a NetworkPolicy for that namespace, which only allows network traffic between Pods which are in the same Project.
It’s very frustrating that if I try to install a service mesh framework such as Istio or Linkerd, and I put their namespaces into a Project, and then, things break!
So I’m wondering is there any method or workaround to allow network traffic across Projects?
