I’m new to Kubernetes. Yesterday, I set up MetalLB and was able to assign IP addresses to all services in the default namespace. However, when I try to do the same with services in another namespace, they only show as <pending>. Can anybody please help me with this?

This is my IP Pool I know it is a tiny one but I don’t need more.

apiVersion: metallb.io/v1beta1
kind: IPAddressPool
metadata:
  name: first-pool
  namespace: metallb-system
spec:
  addresses:
    - 192.168.56.16-192.168.56.19

and this is my L2Advertisement

apiVersion: metallb.io/v1beta1
kind: L2Advertisement
metadata:
  name: example
  namespace: metallb-system
spec:
  ipAddressPools:
  - first-pool

Like the official guide said the ARP is setup up
