The RDPlus Gateway feature has many benefits for larger Terminal Server environments.

It allows you to assign servers to users or groups. Doing so, your users will be able to access the servers that are assigned to them.
You will also be able to configure the load balancing for your RDPlus server farm. This feature is useful if you plan on having a large number of users (>50).

Gateway Tab

Open the Admin Tool and click on the Gateway tile:

Overview

To use the Gateway features, one server must be set as the Gateway / master server of your server farm.

  • You can Add/Edit/Remove servers from your farm.
  • You can assign one or several servers to a user / a local group / an Active Directory group.

According to their log on credentials, the user will be able to choose which server they wants to access in the list of servers assigned to them.

If the farm is within a Domain, the Gateway will use their AD credentials and the user will connect with Single Sign-On (SSO). Otherwise, they must have the same local credentials on each server.

Managing the Servers of the Gateway

To manage the servers please click on the “Servers list Management” tile. The window “Add, Edit or Remove Servers from your Gateway Portal” will open:

When you click on the “Add a new Server” button you can then add an RDPlus Server by Display name and IP address (you can type an IP or a domain name, with or without a port number):

When you are done, please click the “Save” button to add the server to the Servers list.

To remove a server from the Servers list, click on the server you want to remove and then click on the “Remove Server” button.
After a confirmation message, the server will then be removed from the list.

You can also edit a server by selecting it on the list and clicking on the “Edit Server” button.
The “Manage Users” button is explained in Managing Gateway Users.

RDPlus Server Farm Architecture

There are 2 options to deploy an RDPlus server farm:

Option 1: All your servers have public IP addresses and can be reached from the Internet. OR:

Option 2: Only the Gateway Portal can be reached from the Internet. The Gateway is providing a “Reverse Proxy Role”.

In both options:

  • Every server has the same RDPlus configuration.
  • Every server has the same HTTP/HTTPS ports.
  • To publish a new Application just add it the AdminTool on the Gateway Portal.

Of course, make sure that this application is installed on the targeted Application Servers.
All Web Access types are available without any specific configuration: Native, JAVA and HTML5 clients.

In the Admin Tool, click on the Web tile, then click on the Web Portal Preferences tile.

Check the “Generate a Gateway Portal enabled Web Page” box, then click on “Publish”.

Option 1 – All Servers have their own Public IP Address and can be reached from the Internet.

This is the recommended architecture to use RDPlus Gateway.

This architecture follows best practices and allows the IT Administrator to industrialize its environment:

  • Every server has the same Terminal Service Plus configuration
  • Every server has the same HTTP/HTTPS ports
  • Deploying a new Application server is only a matter of minutes (just add the server to the farm in the AdminTool on the Gateway server)

With this architecture, all access types are available without any specific configuration: Native, JAVA and HTML5 clients.

This architecture is described in the diagram below:

Option 2: Only the Gateway Portal can be reached from the Internet and includes a “Reverse Proxy Role”.

Terminal Service Plus Gateway can also be set up with only 1 Public IP Address.

The Gateway redirects any external connection request to any available server. If you do not use the load balancing feature, users will connect to their assigned server(s).

This architecture is described in the diagram below:

For more information about the Reverse Proxy Role, see the Reverse Proxy Feature documentation.

RDPlus Server Farm Without Load Balancing

You can set a range of Application Servers. Each of them with different types of applications (Accountancy Server, Payroll Server, Office Automation Servers…).
In such deployment, the Administrator will enter a list of servers and will assign servers to users.
For example, the user John will be allowed to access to the 3 servers, but the user Paul will have access only to the Payroll Server.

To setup this kind of Farm, please read: Managing Gateway Users

Load Balancing and Failover :

When the load balancing feature is activated, the user does not select the Server where their session will run.
The RDPlus load balancer will check which server is less loaded and will assign it to the incoming user request.
To setup a load balanced server farm, please read: Load Balancing
