The TS Agent assigns each user on a Microsoft Terminal Server a port range and distributes the user/port information to a configurable list of CloudGen and X-Series Firewalls. Install and configure the Barracuda TS Agent on your Microsoft Terminal Servers, and Citrix Desktop running on Microsoft Terminal Servers. Then configure your CloudGen Firewall to get user information from the Barracuda TS Agent.
By default, connections with the Barracuda TS Agent are SSL encrypted. To authenticate the remote TS Agent on the terminal server, use SSL client certificates. If no SSL certificates are configured, all incoming SSL connections are accepted.

Configuration Section | Description |
---|---|
List of Barracuda Unit(s) IPs | The management IP addresses of the firewalls that must receive user information from the Barracuda TS Agent. If the agent cannot establish a connection, it retries until it is successful. If you configured a non-default port, you can add it using the |
Identity | The certificate and private key for communicating with the firewalls. With this certificate, firewalls can verify the identify of the Barracuda TS Agent. |
Port Assignment | The ports that are assigned to users and how to handle connections when ports are not available. You can configure these settings:
|
User Port Range (Requires a system restart) | The port range from which users are assigned their own ranges, excluding any reserved reserved ports. The number of these ranges is the number of users possible on the server. The range must have at least 100 ports, be large enough to hold at least 5 users, and not overlap with the system port range. If you set Prefer to Connectivity, ensure that the user port range does not overlap with the port range displayed in the Windows Default Port Range(s) section. |
System Port Range | The port range for the Microsoft Windows built-in 'System' user. The range must be at least 100 ports and not overlap with the user port range. If you set Prefer to Connectivity, ensure that the system port range does not overlap with the port range displayed in the Windows Default Port Range(s) section. |
Windows Default Port Range(s) | (Read-only) Displays the ephemeral port ranges that are normally used by Windows if the Barracuda TS Agent does not change them. If you set Prefer to Connectivity , ensure that other port ranges do not overlap with the Windows default port range because the Barracuda TS Agent lets the OS assign a port number from the Windows default port range when there are no user or system ports available. |
Advanced | This section offers the option to configure MSAD Domain Controller credentials.
