In IAG, we created Basic and Webmail trunks to publish a single Web application with a one-to-one connection, where one external IP address routes to a single backend Web application server. Basic and Webmail trunks are no longer available in UAG, so what happens now if you want to publish a single Web application directly, rather than requiring users to access an application via a UAG portal?
Basic and Webmail trunks provided limited functionality in IAG, and UAG aims to provide direct Web application publishing with the same flexibility and feature set as portal application publishing. In order to do this, UAG introduces a new feature known as application-specific public host names. For ISA Server/Forefront TMG users, this feature is similar to the link translation feature, and in UAG it provides an alternative to the HAT mechanism.
Using an application-specific public host name, you can publish Web applications directly via a portal trunk. When a user types the application public host name in a browser, rather than the portal public host name, the client endpoint connects directly to the application. When the UAG server receives a request for an application-specific host name, it performs authentication, and then automatically opens the required application, bypassing the UAG portal home page. One issue to note - although this option allows users to access a Web application directly, it does require them to remember a public host name for each application published in this way.
After completing the wizard, do the following:
