Hi,
I configured HAProxy as a reverse proxy. I would like te see in the acceslogs of my nginx webserver the original client IP issueing the request. Therefore I configured HAProxy as follows:
global
log /dev/log local0
log /dev/log local1 notice
chroot /var/lib/haproxy
stats socket /run/haproxy/admin.sock mode 660 level admin expose-fd listeners
stats timeout 30s
user haproxy
group haproxy
daemon

log global
mode tcp

option dontlognull
timeout connect 5000
timeout client 50000
timeout server 50000

errorfile 403 /etc/haproxy/errors/403.http
errorfile 408 /etc/haproxy/errors/408.http

errorfile 502 /etc/haproxy/errors/502.http

Within the nginx.conf I added:
log_format main '$http_x_real_ip - $remote_user [$time_local] ' '"$request" $status $body_bytes_sent ' '"$http_referer" "$http_user_agent"'; access_log /var/log/nginx/access.log main; error_log /var/log/nginx/error.log main;
extract from the nginx access.log
"- - - [26/Feb/2021:08:07:16 +0100] "GET / HTTP/2.0" 403 181 "-" "Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/78..3904.108 Safari/537.36"
Has anybody got a clue and a hint for me, why the IP is not shown in the nginx access.log or error.log
Thank you
