You shouldn’t need to modify that specifically, unless you don’t want to check for the standard headers and want to force REMOTE_ADDR to be the value of HTTP_X_FORWARDED_FOR.

I tested this on a source compile of NGINX using the following fastcgi configuration:

fastcgi_connect_timeout 60;
fastcgi_send_timeout 180;
fastcgi_read_timeout 180;
fastcgi_buffer_size 512k;
fastcgi_buffers 512 16k;
fastcgi_busy_buffers_size 1m;
fastcgi_temp_file_write_size 4m;
fastcgi_max_temp_file_size 4m;
fastcgi_intercept_errors off;

fastcgi_param SCRIPT_FILENAME   $request_filename;
fastcgi_param PATH_INFO         $fastcgi_path_info;
fastcgi_param PATH_TRANSLATED   $document_root$fastcgi_path_info;
fastcgi_param QUERY_STRING      $query_string;
fastcgi_param REQUEST_METHOD    $request_method;
fastcgi_param CONTENT_TYPE      $content_type;
fastcgi_param CONTENT_LENGTH    $content_length;
fastcgi_param SCRIPT_NAME       $fastcgi_script_name;
fastcgi_param REQUEST_URI       $request_uri;
fastcgi_param DOCUMENT_URI      $document_uri;
fastcgi_param DOCUMENT_ROOT     $document_root;
fastcgi_param SERVER_PROTOCOL   $server_protocol;
fastcgi_param REQUEST_SCHEME    $scheme;
fastcgi_param HTTPS             $https if_not_empty;
fastcgi_param HTTP_PROXY        "";
fastcgi_param GATEWAY_INTERFACE CGI/1.1;
fastcgi_param SERVER_SOFTWARE   nginx/$nginx_version;
fastcgi_param REMOTE_ADDR       $remote_addr;
fastcgi_param REMOTE_PORT       $remote_port;
fastcgi_param SERVER_ADDR       $server_addr;
fastcgi_param SERVER_PORT       $server_port;
fastcgi_param SERVER_NAME       $server_name;
fastcgi_param REDIRECT_STATUS   200;

The above is what would normally be in the fastcgi_params file.
