Question Plesk behind a load balancer and Cloudflare (IP)

[cytslm]

Hello everyone.
I have a quick question to see if you can help me.

I have PLESK installed on a virtual machine that is behind a load balancer, and all requests come through Cloudflare to the LB.
Client -> Cloudflare -> Load Balancer -> Plesk (server & webs)

In the LB I unmask the real IP of the client.
But, in Plesk I get the IP of the load balancer (LB) instead of the client.

I have fixed it by editing the /etc/apache2/plesk.conf.d/server.conf file

And adding the IP of the LB at the end of
# RPAFproxy_ips
# RemoteIPInternalProxy
And now I can have the true IP of the client after coming from Cloudflare and going through the LB

Is this how it should be done?

The only problem is that if I touch the Plesk configuration the server.conf file is re-configured and I have to put the previous configuration back.

Thank you!

Hello @cytslm

I think you will find what you need in this help article. It does also provide a script for nginx, which does update the config with the IPs from Cloudflare. Based on which load balancer you are using, you can edit this script for your needs (support from your load balancer provider should be able to help you with this).

Hope this helps
