You can set a custom header for example X-Forwarded-For and set the user IP to that header. You can use that header on the other site and work with them. Some loadbalancers do exactly the same and use a custom header for the user ip.

curl_setopt($ch, CURLOPT_HTTPHEADER, array(
    'X-Forwarded-For: ' . $externalIpAdress,
));
