title: How do I use proxy protocol version 2 to get client's real IP address with AWS Network Load Balancer?
body: <p>Currently we are passing our requests through an AWS Network Load Balancer and then onto an AWS Application Load Balancer.  However, we are trying to preserve the original IP address of the request, but this is being stripped out.  We are attempting to enable Proxy Protocol v2, but this causes error. Does the AWS ALB speak proxy protocol v2?</p>
