I am testing RD Gateway with Azure MFA NPS extension. So far I have managed to successfully get this to work using one RD Gateway server, a central NPS server and Azure MFA NPS extension installed on the central NPS server. I have tested this and all works fine, I RDP to a RD session host / collection via the gateway server, then I get prompted on phone to approve connection, then the connection resumes and desktop appears. However I need to add a second RD Gateway that has a different public facing SSL certificate to the one I have working, but it also needs to use Azure MFA, therefore what I am trying to achieve is having 2 RD Gateway servers, both talking to one central NPS server with the Azure extension installed and configured. Unfortunately I cannot seem to get this working. It works so far as I can initiate the connection, I receive prompt on phone to approve connection, but somehow this does not get back to the gateway server to continue the connection. Firstly has anyone else managed to setup more than one RD Gateway to work with a Central NPS server for Azure MFA? If not will it require a second NPS server for the additional RD gateway server?
Any help on this would be grateful.
RD Gateway Server(s) are Server 2019
Central NPS Server is Server 2019 - Using latest downloadable version of Azure MFA NPS Extension (220.127.116.11)
RD Session Host Server is Server 2016, which also has connection broker role installed and configured. Regards, Scott S.
