Duo Authentication for Remote Desktop Gateway adds two-factor authentication to your RemoteApp Access logons, and blocks any connections to your Remote Desktop Gateway server(s) from users who have not completed two-factor authentication when all connection requests are proxied through a Remote Desktop Gateway. Users automatically receive a 2FA prompt in the form of a push request in Duo Mobile or a phone call when logging in.
Today, I am going to show you how to deploy simple Remote Desktop Gateway on the Microsoft Windows Server 2019 without complete Remote Desktop Services Infrastructure. It means I don’t have a farm of RD session host servers sitting behind and I don’t want to deploy Connection broker, web access and session host server (e.g. complete infrastructure).
