I have services with ClusterIP in Kubernetes and using nginx (https://github.com/helm/charts/tree/master/stable/nginx-ingress) to expose these services to the internet. When I try to get client IP address in application I am getting cluster's node IP. How can I retrieve actual client IP?

I looked into "externalTrafficPolicy": "Local" settings in service but for that service type must be LoadBalancer.

I also tried update ingress annotations with:

nginx.ingress.kubernetes.io/enable-cors: "true"
nginx.ingress.kubernetes.io/cors-allow-headers: "DNT,X-CustomHeader,Keep-Alive,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type,Authorization,X-Forwarded-For,csrf-token"
nginx.ingress.kubernetes.io/cors-allow-origin: "https://example.com"

But, still, it's not working. Please advice!
