Configure a VPN Server for NAP
Applies To: Windows Server 2008, Windows Server 2008 R2, Windows Server 2012, Windows Server 2012 R2
A NAP VPN server is a server running Windows Server® 2008 or Windows Server 2008 R2 with the Routing and Remote Access role service installed. Because Routing and Remote Access can forward connection requests to a RADIUS server, this is the only NAP enforcement server that does not also require that Network Policy Server (NPS) is installed as a RADIUS proxy if the NAP health policy server is located on another computer. The NAP VPN server restricts access to noncompliant NAP clients by applying packet filters to the client VPN connection. Packet filters are configured on the NAP health policy server.
Membership in the local Administrators group, or equivalent, is the minimum required to complete this procedure. Review details about using the appropriate accounts and group memberships at Local and Domain Default Groups (http://go.microsoft.com/fwlink/?LinkId=83477).
