In Hazelcast, you can configure the Hazelcast members with separate server sockets using a different network configuration for different protocols. It is called Advanced Network and support Member, Client, REST, Memcache and WAN protocols.
In the Hazelcast Platform Operator, advanced networking configuration is enabled by default and REST and Client protocols are already configured:
- 
For Client protocol the port number is 5701.
- 
For REST, port number is 8081andPersistence,HealthCheckandClusterWriteendpoint groups enabled by default.
- 
For WAN, default port number is 5710.
You can configure Member Protocol interfaces and WAN Protocol sockets using the Hazelcast Platform Operator.
Configuring Member Protocol Interfaces
This is an example configuration for configuring interfaces using the Hazelcast Platform Operator:
apiVersion: hazelcast.com/v1alpha1
kind: Hazelcast
metadata:
  name: hazelcast-sample
spec:
  clusterSize: 3
  repository: 'docker.io/hazelcast/hazelcast-enterprise'
  version: '5.3.1-slim'
  licenseKeySecretName: hazelcast-license-key
  advancedNetwork:
    memberServerSocketEndpointConfig:
      interfaces:
      - 10.10.1.*Configuring WAN Protocol Sockets
The following example shows an example configuration for configuring WAN sockets using the Hazelcast Platform Operator:
apiVersion: hazelcast.com/v1alpha1
kind: Hazelcast
metadata:
  name: hazelcast-sample
spec:
  clusterSize: 3
  repository: 'docker.io/hazelcast/hazelcast-enterprise'
  version: '5.3.1-slim'
  licenseKeySecretName: hazelcast-license-key
  advancedNetwork:
    wan:
    - name: istanbul
      port: 5710
      portCount: 5
      serviceType: LoadBalancerPossible values for serviceType are: ClusterIP and LoadBalancer. After applying this example configuration, there will be 1 service created with type of LoadBalancer which exposes 5 ports: 5710, 5711, 5712, 5713, 5714. If you don’t provide a serviceType, it will be set to LoadBalancer by default.
| In case WAN Replication configuration is not provided in advancedNetworkconfiguration, port number5710will be configured for WAN Replication by default. |
