Problems with PROXY_PROTOCOL in ngx_stream

Mon Sep 9 08:17:17 UTC 2019

I am using ngx_stream with ssl_preread_module. The $ssl_preread_server_name
variable is used in the proxy_pass directive. Nginx is behind NLB in AWS and
receives v2 of the protocol with Amazon's own extension - PP2_TYPE_AWS -
https://docs.aws.amazon.com/elasticloadbalancing/latest/network/load-balancer-target-groups.html#proxy-protocol

The problem I am running into is the fact nginx does not pass the original
proxy_protocol header so the upstreams can not see the PP2_TYPE_AWS field
from the original header.  Any advice?
