Estoy intentando configurar una conexión VPN desde mi Macbook (OSX High Sierra) a la Vodafone Station Revolution de mi oficina. Esta es una parte del archivo ppp.log que muestra lo que sucede:

Parece que la conexión está establecida, pero entonces no hay respuesta a la solicitud de configuración. ¿Hay algún servicio o puerto que deba verificarse?
La VPN funciona bien con el protocolo PPTP pero, como ya no es compatible con Apple, necesito encontrar una forma de conexión a través de L2TP.
¿Alguna idea?
