I have been trying to get real ips to show up in Discourse without much success. I have add the cloudflare yml to my setup and have validated the discourse.conf in the container has the correct lines: set_real_ip_from 173.245.48.0/20; set_real_ip_from 103.21.244.0/22; set_real_ip_from 103.22.200.0/…

I don’t know. Maybe you need to include some docker IPs? Is the IP that’s getting displayed by Discourse a docker ip?

Maybe use the cloudflare template? add - "templates/cloudflare.template.yml" to your app.yml where the other templates are.

Thanks for the response! I am using the cloudflare template. After further digging it appears that it is not working because all remote_addr coming into nginx are Docker addresses. I am trying to diagnose why this is.

Are you also using a local reverse proxy server? If so, you’ll need to add that address to your set_real_ip config (and maybe the reverse proxy will handle the cloudflare stuff?)

I am not intentionally running a reverse proxy but I have specified a specific IP for exposing ports in my app.yml. expose: - "xxx.xxx.xxx.xxx:80:80" # http - "xxx.xxx.xxx.xxx:443:443" # https

[image] bitwelder: I am not intentionally running a reverse proxy Did you follow the standard install ? This usually works out of the box with the template.

Thank you both for the help! It ended up that Immunify360 on our VPS was injecting itself as a proxy prior to the container. Adding the Docker IP to the set_real_ip_from temporarily fixed the issue while I look into disabling Immunify.
