I'm currently using OpenVPN on Linux which uses AES-NI for a significant performance improvement. Since not all devices have an openvpn client available, I would like to add L2TP and SSTP vpns using Windows Server 2012. Unfortunately I am not finding anything about whether Routing and Remote Access in Windows 2012 uses AES-NI when the cpu supports it.
Does RRAS in Windows Server 2012 use Intel's AES-NI on supported cpus to speed up L2TP vpns that use AES encryption?
Can Windows Server 2012 utilize AES-NI for SSTP vpns, which goes through IIS?
