What is NPS in RADIUS?
When you configure Network Policy Server (NPS) as a Remote Authentication Dial-In User Service (RADIUS) proxy, you use NPS to forward connection requests to RADIUS servers that are capable of processing the connection requests because they can perform authentication and authorization in the domain where the user or computer account is located. For example, if you want to forward connection requests to one or more RADIUS servers in untrusted domains, you can configure NPS as a RADIUS proxy to forward the requests to the remote RADIUS servers in the untrusted domain.

What is a Radius server?
RADIUS (Remote Authentication in Dial-In User Service) is a network protocol for the implementation of authentication, authorization, and collecting information about the resources used. It is designed to transfer information between the central platform and network clients/devices.
