VPN on Mac works but not my iOS 7 devices
I am running OS X Mountain Lion Server 2.2.2 with the VPN switch on. I have no problem with my MBP connecting to the VPN server, however since upgrading to iOS 7 on my devices they will not connect. I keep receiving the following error. All the correct ports are forwarded and I am using an Airport Extreme as my router. This boggles my mind because VPN worked just fine on iOS 6, please help.
"The L2TP-VPN server did not respond. Try reconnecting. If the problem continues, verify your settings and contact your Administrator."
iPhone 4S, iOS 7.0.2
