I'm trying to find an article on how to configure TS Web Access so a domain user can authenticate to a TS Web server via TS Gateway from outside. I have configured two Windows server 2008 R2 Standard servers, 1 as a TS Gateway with external access (terminal.blabla.ca) and 1 as TS Server which has a few apps installed such as MS Office, Adobe Acrobat, etc. This all works fine when using a RDP file, the user connects to the remote server easily thru the Gateway but when trying with the web access I can't get it to work from outside. It works fine inside obviously when typing the URL, I get redirected to the TS web access on the TS Server with access to the apps. I have installed Remote Desktop Web Access Role on both machines and Remote Desktop Gateway Role on only one with a 3rd party SSL Cert. The fact that everything works fine with a RDP file makes me think that I'm not far but still not there!
