 The apache image will replace the remote addr (IP address visible to Nextcloud) with the IP address from `X-Real-IP` if the request is coming from a proxy in `10.0.0.0/8`, `172.16.0.0/12` or `192.168.0.0/16` by default. If you want Nextcloud to pick up the server host (`HTTP_X_FORWARDED_HOST`), protocol (`HTTP_X_FORWARDED_PROTO`) and client IP (`HTTP_X_FORWARDED_FOR`) from a trusted proxy, then disable rewrite IP and add the reverse proxy's IP address to `TRUSTED_PROXIES`.
