Gateway Feature

Terminal Service Plus Gateway has a lot of benefits.
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 farm of TSplus servers. This feature is useful if you plan on having a large number of users.

Overview

A server can be set as the Gateway of your farm of servers.

According to his credential, the user will be able to choose which server he wants to access in the list of servers assigned to him.

If the farm is within a Domain, the Gateway will use his AD credentials and the user will connect with Single Sign-On (SSO).
Otherwise, he 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:

TSplus Farm of Servers Architecture

There are 2 options to deploy a TSplus farms of servers:

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:

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 Terminal Service Plus Gateway.

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

With this architecture, all access types are available without any specific configuration: Remoteapp 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.

TSplus farm of Servers 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 is activated, it is no more the user who select the Server where he is going to open a session.
It is the TSplus load balancer which checks which server is less loaded and will assign it to the incoming user request.
To setup a load balanced Farm of Servers, please read this page.
