This is directly related to Q ID: 24687836 ;
I have a Cisco ASA firewall that currently passes on remote access VPN user authentication to a Windows 2000 IAS RADIUS server. I wish to move this to a Windows 2008 x64 server.
I have tried configuring NPS on Windows 2008 to accept RADIUS requests to no avail - testing from the Cisco firewall indicates that the server is not responding.
I need to understand how this authentication works in IAS, and what needs to be done in NPS to make this functional ( I have the NPS service running, but feel that Routing & Remote access server should not be needed).
Our IAS config is very basic. We are allowing domain users to connect - but I am unable to see anything that specifically relates to the firewall (as a RADIUS client, policies).
What I'd like to know;
1) Is anyone using Windows 2008 (64 bit) NPS as a RADIUS server to authenticate Cisco VPN clients?
2) If so, how is this accomplished (services, RADIUS client setup, policies)
3) How does RADIUS authetication work in IAS (in light of above)
I appreciate all input on this - I've had a consultant in to help to no avail, and a call to Cisco support (from consulted) resulted in the fact that they don't know how to set it up either.....
