How to properly use X-Forwarded-For in v2?

I was struggling with this for a configuration that was behind an Amazon application load balancer. The solution is simple, but for some reason I never got the combination of config items correct until today. Here's what we're using, where 10.0.0.0/16 is our VPC subnet.

  web:
    address: ":80"
    proxyProtocol:
      trustedIPs:
        - "10.0.0.0/16"
    forwardedHeaders:
      trustedIPs:
        - "10.0.0.0/16"
  websecure:
    address: ":443"
    proxyProtocol:
      trustedIPs:
        - "10.0.0.0/16"
    forwardedHeaders:
      trustedIPs:
        - "10.0.0.0/16"
