When publishing RD Web, it is recommended to use the same internal and external FQDN. For more details see Support for client configurations. Your end users must use a compatible browser to connect to RD Web or the RD Web client. To learn which ports need to be opened, and other details, see Tutorial: Add an on-premises application for remote access through Application Proxy in Azure Active Directory. Ensure you have satisfied the pre-requisites to enable Application Proxy, such as installing the connector, opening required ports and URLs, and enabling TLS 1.2 on the server. You should already have deployed RDS, and enabled Application Proxy. RD Web and RD Gateway are published as a single application with Application Proxy so that you can have a single sign-on experience between the two applications.
Both the RD Web and RD Gateway endpoints must be located on the same machine, and with a common root.
