Hello everybody
I tried to set up a Remote Desktop Gateway Infrastructure with a NPS Server for authentication. The Remote Desktop Gateway is in the DMZ and not joined to our Active Directory. In our coorperate Network with the DC in it i installed a NPS Server which is
joined in the Active Directory, i want to use this server for authentication. I tried so many things and configurations but the Domain User can't log in with their login. Please look at the attached situation plan.
Is there any possibility to do this whitout joining the RDGW to the Domain?

Thanks for helping
