Has anyone attempted to use the RRAS role in Windows 2008R2 to provide a basic VPN solution? I've been doing this for ages using a username and password but I need to extend the solution by authenticating with a cert. I'm running into a problem on the NPS side of things I think. Can anyone offer a fresh perspective please? I've been working on this for 2 hours now and I'm getting nowhere. Even a suggestion as to where I'd find logs would be beneficial. Thanks Darragh
