Issue nginx + apache + plesk = wrong REMOTE_HOST value

[Kitty]

Hi there,

Im running the latest plesk onyx (web admin) on apache2 + nginx on an Ubuntu 16.04 vps.

My issue is that after enabling HostnameLookups in apache2.conf, the REMOTE_HOST value contains the domain name of the website, not the hostname based on the user's IP.

This value is only wrong when I access the server via nginx (port 80), if I connect directly to apache via port 7080 it's correct.

Is this a plesk issue or apache?

Is this explain somewhat of your issue?

IP address restrictions in .htaccess do not work properly if nginx is enabled

nginx proxies requests to Apache via the "rpaf" module so that in Apache logs, we see the real IP of a site visitor. But in fact, the connection between nginx and Apache is established using local server IP addresses, and Apache applies IP restrictions to local IP addresses.

Ah yes I've tried the rpaf module. It actually makes "REMOTE_HOST" correct, but it then unfortunately breaks the "REMOTE_ADDR" values (becomes the server public IP).

The remoteip module is running on the server, which supposedly superceded rpaf a few years ago. I believe this module (remoteip) is the reason why the REMOTE_ADDR contains the correct client IP address, but fails with REMOTE_HOST.
