Ho installato un server Mac OS X 10.8 che esegue il servizio VPN. Dal mio Mac posso connettermi al server VPN senza problemi, ma i dispositivi iOS non sono tutti in grado di connettersi.
La console visualizza il seguente messaggio durante il tentativo di connessione di un iPhone:

iOS mostra il seguente messaggio di errore: "Il server L2TP-VPN non ha risposto. Prova a riconnetterti. Se il problema persiste, verifica le impostazioni e contatta l'amministratore."
Perché non riesco a connettere un iPhone al server VPN mentre un Mac non ha problemi di connessione?
