He configurado un servidor Mac OS X 10.8 que ejecuta el servicio VPN. Desde mis Mac, puedo conectarme al servidor VPN sin ningún problema, pero los dispositivos iOS no pueden conectarse.
La consola muestra el siguiente mensaje al intentar conectar un iPhone:

iOS muestra el siguiente mensaje de error: "El servidor L2TP-VPN no respondió. Intente reconectarse. Si el problema continúa, verifique su configuración y póngase en contacto con su administrador".
¿Por qué no puedo conectar un iPhone al servidor VPN mientras que una Mac no tiene problemas para conectarse?
