Saving a Remote IP Client Using Ingress

Question

My goal is to make my web application (deployed on a Kubernetes 1.4 cluster) look at the IP address of the client who originally made the HTTP request. Since I plan to run the application on a bare group, the GCE and service annotations service.alpha.kubernetes.io/external-traffic: OnlyLocalintroduced in 1.4 are not applicable to me.

Looking for alternatives, I found this question that suggests setting Ingress to achieve my goal. So, I installed Ingress and NginX Ingress Controller . The deployment went smoothly and I was able to connect to my web application through Ingress Address and port 80. However, in the logs I still see the range of IP addresses within the cluster (from 172.16.0.0/16), which means that the external IP client Addresses do not pass properly through Ingress. Could you tell me what I need to configure in addition to the above to make it work?

My Ingress Configuration:

apiVersion: extensions/v1beta1   
kind: Ingress
metadata:
  name: myWebApp
spec:
  backend:
    serviceName: myWebApp
    servicePort: 8080
