Our Magento 1.9.0.1 admin panel shows 127.0.0.1 for all online customer instead of the real IP address. Due to the wrong IP I can not use an important payment gateway. Does anyone know what can be wrong and what can I check? The Extension support from Klarna Payment tells us, that anything in magento is configured wrong. We update our Store from 1.5 to 1.9. All other parts work fine. Thanks in advance. Best Jun
Are you using any layer between user and the app-server for ex. Varnish? If yes this is probably the issue - because the appservers receives the IP of the service and not the original user.
Do a var_dump($_SERVER); and normally U use the REMOTE_ADDR key to get the users IP but if there is an additional service in the middle this value will probably be the IP of the service, look for the key HTTP_X_FORWARDED_FOR and verify whether it is the IP you need.
