Cilium Network Policy

I have a microk8s one node cluster set up. When enabling Cilium network policies I cannot access the whoami webpage; however, I can access it fine without the network policy or if I uncomment the fromEntities and toEntities “all” parts. Can anyone help me with what I am doing wrong please?

#    - fromEntities:

    - fromCIDR:
      - "192.168.1.0/24"

So, I’ve narrowed down the issue. It appears fromCIDR and toCIDR is not functioning how it should be and allowing traffic from outside the cluster. I know this because if I uncomment the “fromEntities - world” and “toEntities - world” parts, I can access whoami via the nodeport services. Could I possibly get some help please? Why isn’t fromCIDR and toCIDR working?
