Does anyone know how to get Azure MFA server working when the MFA server is installed on a domain controller that is already running NPS. Event logs on the MFA server just say A RADIUS message was received from the invalid RADIUS client IP address **.**.160.3


Works fine if i install the MFA on a different server, the only problem is the other server is at the end of a VPN and is a little slow to communicate with Azure

I think the problem lies with that two RADIUS service are using the same ports.

Did you changed this in the Azure MFA Server configuration to use alternative ports?

Yes, I've changed the ports but still get the same issue.

The issue is that you have not set up the nps server to receive requests form the radius client, which you are sending the requests from.
You needs to configure the NPS server with the correct IP address and shared secret needed to communicate with the client under the NPS radius clients section.
