**5. Service with externalIPs specified**

For service with `externalIPs` specified, IPVS proxier will install IPTABLES with match of ipset `KUBE-EXTERNAL-IP`,
Suppose we have service with `externalIPs` specified, IPTABLES rules should look like what is shown below.

```shell
Chain PREROUTING (policy ACCEPT)

## ref: http://kubernetes.io/docs/user-guide/services/
##
service:
  type: ClusterIP
  clusterIP: ~
  port: "9000"
  nodePort: 32000
  loadBalancerIP: ~
  externalIPs: []
  annotations: {}

  ## service.loadBalancerSourceRanges Addresses that are allowed when service is LoadBalancer
