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:

```plaintext
set_real_ip_from 173.245.48.0/20;
set_real_ip_from 103.21.244.0/22;
set_real_ip_from 103.22.200.0/22;
set_real_ip_from 103.31.4.0/22;
set_real_ip_from 141.101.64.0/18;
set_real_ip_from 108.162.192.0/18;
set_real_ip_from 190.93.240.0/20;
set_real_ip_from 188.114.96.0/20;
set_real_ip_from 197.234.240.0/22;
set_real_ip_from 198.41.128.0/17;
set_real_ip_from 162.158.0.0/15;
set_real_ip_from 104.16.0.0/13;
set_real_ip_from 104.24.0.0/14;
set_real_ip_from 172.64.0.0/13;
set_real_ip_from 131.0.72.0/22;
set_real_ip_from 2400:cb00::/32;
set_real_ip_from 2606:4700::/32;
set_real_ip_from 2803:f800::/32;
set_real_ip_from 2405:b500::/32;
set_real_ip_from 2405:8100::/32;
set_real_ip_from 2a06:98c0::/29;
set_real_ip_from 2c0f:f248::/32;
real_ip_header CF-Connecting-IP;

```

I have also validated that `$http_cf_connecting_ip` has the correct IP in the logs but for some reason `$remote_addr` is not being set properly. Has anyone else hit this?

Maybe use the cloudflare template?

add

```plaintext
  - "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.

```plaintext
expose:
  - "xxx.xxx.xxx.xxx:80:80" # http
  - "xxx.xxx.xxx.xxx:443:443" # https

```

I don’t know. Maybe you need to include some docker IPs?

Is the IP that’s getting displayed by Discourse a docker ip?

Did you follow the [standard install](https://meta.discourse.org/t/142537?silent=true)? 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.
