NPS Proxey Radius configuration problem RRS feed

  • Question

  • Hi

    We have a problem configuring NPS proxy Server to a Radius Server.

    Our client has a Firewall defined as a client to the NPS Radius Server.

    We have a third party Standard Radius Server that is used as a Remote Radius Server.

    We defined:

    -          New  Remote Radius server

    -          Connection Request Policies as Forward requests to the …. remote RADIUS server group for authentication

    The problem:

    When the Firewall requests the authentication, it is passed to the correct Standard Radius server.

    The Standard Radius Server responds correctly to the NPS Server.

    The NPS Server issues a message:   The RADIUS Proxy received an unexpected response from server 172.25.64.33. The data is the RADIUS message.

    The NPS Server continues to send authentication requests, not recognizing the response it gets.

    The Standard Radius Server is working perfectly with other infrastructure systems like: Juniper, Fortigate, Cisco, CheckPoint and others. We only have the problem with EPS.

    Any idea what we are missing ?

  • Hi,

    According to your description, my understanding is that you wanted to use NPS as a RADIUS proxy to forward connection requests to the remote RADIUS server.

    It seems that the issue is related to the event ID 32 and it is because the response messages that the RADIUS server sent is not comply with the RADIUS protocol for use with NPS. In these scenario, please contact your RADIUS server vendor for configuration assistance or software or firmware updates.
