Kubernetes how to transfer real ip clients to pods?

Question

Kubernetes

Good afternoon.
There is a cluster of 3 nodes deployed using kubespray on real hardware (Bare metal). As a network driver/service - flannel. I make a service through NodePort, open access to internal containers. I check the traffic - all traffic comes from ip 10.233.64.0, that is, NAT and source and destination ip occur when accessing the service.
Can someone tell me if it is possible to somehow get real ips of clients that connect from the Internet to the service on the pods in network packets, that is, so that NAT source ip is not done in incoming packets.
Thank you!

Answer 1

Setting the service.spec.externalTrafficPolicy property to Local for a NodePort service will force the request to be proxyed to the local node only and prevent NAT.
