The goal is to set up RD services in order to allow external users to connect externally and then Remote Desktop to a terminal server instead of using port 3389 and RDP. I have an SSL cert configured and port 443 assigned from public IP to internal IP of the RD Gateway server. Externally, I enter in https://remote.domain.com/rdweb and I get the website and can log in. once I log in, I see the connected to remoteapp and desktop connection in the system tray. If I go to the remote desktop tab of rdweb, and enter either of the terminal servers, it prompts me again to log in, and after entering in the credentials, I get an error stating your computer can't connect to the remote computer because the remote desktop gateway server is temporarily unavailable. that message is attached. This error is on a windows 10 machine. If I use Windows 7, I enter in the credentials and the login page keeps prompting me to login in and no errors, just the login keeps popping up again.
In IIS, under RDWeb and pages, I have the defaultTSgateway set to remote.domain.com.
In RD Gateway manager, I have both the RD Cap and RD Rap configured
In RD Licensing Manager, I have 10 CALs set up and activated.
Internally, I can connect through RDWeb and enter in the terminal server name on the remote desktop tab and launch the desktop.
I have a Network Police Server set up on the RD Gateway and configured to that of a working RD Gateway environment I have set up at another client.
I also attached the remote desktop services that I have installed. I do think I dont need everything showing.
I have researched and researched and seems I have tried everything I could find. There are not many logs in event viewer showing anything of importance.
