Whitelisting Cloudflare IP's on AWS K8s cluster

Hello,

I need to restrict access of IPs to just Cloudflare on AWS Network load balancer. We have a Kubernetes cluster running with a network load balancer. Does anyone know where I need to make this change?

We are seeing attempts bypassing Cloudflare and going directly to our load balancer and we need to prevent this.

Thanks!

This would likely be something that you would have to configure with the VPC.

This is more on the AWS side rather than the Cloudflare side though.

Please refer to:
https://docs.aws.amazon.com/vpc/latest/userguide/vpc-network-acls.html
or

As Jake said, this is more related to AWS and not Cloudflare itself.
