hello,
I have installed server 2012 R2 on my server for the RRAS role. When I configure L2TP Protocol with Pre-shared Key(under custom ) instead of machine certificate authentication the IKEv2 VPN stops working for clients ending up in hanging pn Windows 7 and showing error IKE auth credentials are unacceptable in Windows 8, In order to let IKEV2 VPN work I deselect the "Allow custom IPSEC policy for L2tP/IKE2" connections. This type of behaviour is not seen in Windows Server 2008 R2 why this is happening in server 2012 R2
Please assist.
