I have written this up as a StackOverflow question here: https://stackoverflow.com/q/48195311/2081835.
When adding PROXY v2 with AWS VPC PrivateLink connected to a Network Load Balancer, the endpoint ID of the connecting account is added as a TLV. I need to use this for routing frontend to backend, but I cannot sort out how. Is there a way to call a custom matcher that could do the parsing logic, or is this already built-in and I'm just not finding the documentation? Any ideas on the topic would be super helpful. Thank you.
