Since the cost of building a Load Balancer cluster is too high, I want to directly set up a Network Load Balancer on GCP and forward the traffic directed to this Load Balancer to a specified IP Address List (my private Kubernetes cluster), similar to the effect of HAProxy. However, after going through the documentation, I couldn’t find how to set IP Addresses in Target Pools.

When I try to create a load balancer from the Google Cloud Console it fails and my progress is not saved.
