Nginx proxying TCP Socket Connections is altering original IP - nginx

Question

I am using the current configuration and running it as root:
user nginx;
worker_processes 1;
error_log /var/log/nginx/error.log warn;
pid /var/run/nginx.pid;
events {
worker_connections 1024;
}
stream {
upstream web {
server 127.0.0.1:8445;
}
upstream tcpsocket {
server 127.0.0.1:8444;
}
map $ssl_preread_alpn_protocols $upstream {
"" tcpsocket;
default web;
}
server {
listen 443;
proxy_pass $upstream;
ssl_preread on;
}
}
http {
include /etc/nginx/mime.types;
default_type application/octet-stream;
log_format main '$remote_addr - $remote_user [$time_local] "$request" '
'$status $body_bytes_sent "$http_referer" '
'"$http_user_agent" "$http_x_forwarded_for"';
access_log /var/log/nginx/access.log main;
sendfile on;
#tcp_nopush on;
keepalive_timeout 65;
#gzip on;
include /etc/nginx/conf.d/*.conf;
server {
listen 80 default_server;
server_name _;
return 301 https://$host$request_uri;
}
server {
listen 8445 ssl;
server_name 127.0.0.1;
ssl_certificate_key /etc/nginx/cert.key;
ssl_certificate /etc/nginx/cert.crt;
ssl_protocols TLSv1.2;
location / {
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
# Fix the “It appears that your reverse proxy set up is broken" error.
proxy_pass http://localhost:8443;
proxy_read_timeout 90;
proxy_redirect http://localhost:8443 https://127.0.0.1;
}
}
}
With a requirement to have only one port open (443), I am trying to:
Dispatching http requests to 127.0.0.1:8443 eventually after handling ssl
All "other" requests (I only expect tcp socket connections) to a tcp socket server running at 127.0.0.1:8444
This configuration is working perfectly except that the caller IP changes to 127.0.0.1 for tcp connections.
I don't care about the http caller IP.
I tried the following solutions:
server {
listen 443;
proxy_pass $upstream;
ssl_preread on;
proxy_bind $remote_addr:$remote_port transparent;
}
This causes upstream timed out (110: Connection timed out) while proxying connection
server {
listen 443;
proxy_pass $upstream;
ssl_preread on;
set_real_ip_from 10.0.0.0/8;
real_ip_header X-Real-IP;
real_ip_recursive on;
}
real_ip settings do not work inside the stream block
server {
listen 443;
proxy_pass $upstream;
ssl_preread on;
proxy_protocol on;
}
This causes nginx to fail with error broken header while reading PROXY protocol
Please help!
