Hi.
Follow up question to proxy protocol
Is it possible to handle the Type-Length-Value (TLV) fields in from pp2
in haproxy config or in lua?
I refer to
2.2.7. Reserved type ranges
https://www.haproxy.org/download/1.8/doc/proxy-protocol.txt
from the question on so

routing in HAProxy configuration?
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.
Looks like AWS use the "2.2.7. Reserved type ranges" as described in
https://www.haproxy.org/download/1.8/doc/proxy-protocol.txt therefore
you will need to parse this part by your own.
This could be possible in lua, maybe I'm not an expert in lua, yet ;-)
There are javexamples in the doc link (
https://docs.aws.amazon.com/elasticloadbalancing/latest/network/load-balancer-target-groups.html#proxy-protocol
) which you have added int the stackoverflow request.

Aleks
