In some cases, it might be useful to be able to edit the externalTrafficPolicy and loadBalancerSourceRanges options of the load balancer or node port services. Their value might be in:
- Propagating the real source IP address into the Kafka brokers (externalTrafficPolicy)
- Making sure the routing is more efficient by not routing node port traffic between nodes not hosting the endpoint locally (externalTrafficPolicy)
- Configure the cloud provider firewalls to allow connections only from some IPs (loadBalancerSourceRanges)
