Improve: Show Detected Header Values
-
Hi,
I’d like to suggest a usability improvement for the reverse proxy / firewall settings in the plugin.
Currently, users are asked to select which HTTP header (e.g. REMOTE_ADDR, HTTP_CLIENT_IP, HTTP_X_FORWARDED_FOR) should be used to determine the real client IP address. However, it’s not always clear which one is actually being populated correctly in a given hosting or proxy setup.
It would be very helpful if the plugin could display, next to each option:
* Whether the header is currently set (available in PHP $_SERVER)
* The actual value detected for that headerFor example:
* REMOTE_ADDR → 192.0.2.1
* HTTP_X_FORWARDED_FOR → 203.0.113.45
* HTTP_CLIENT_IP → (not set)This would allow users to easily compare these values with their real public IP address and confidently select the correct option without guesswork.
This small addition could significantly improve the configuration experience, especially for users behind Cloudflare, load balancers, or other reverse proxies.
Thanks for considering this enhancement!
