Hello Experts,
I am facing a weird problem in VPN infrastructure, Recently I decided to upgrade NPS Radius server from server 2008 R2 to Server 2012 R2 now what happening is that when I configure my nps server as in the radius accounting option in Routing and remote access services (RRAS) for VPN User authentication all VPN protocols work fine except IKEv2 if the server on which nps is configured in radius accounting is Server 2012 R2. on server 2008 based RRAS(VPN server) authentication for IKE works fine but on server 2012 based vpn server when my client tries to connect he got stuck at "Verifying username and password" is there some difference in the handling of IKEv in server 2012 R2 and Windows Server 2008 R2.
Please suggest a solution
Thanks
