After installing and configuring the Barracuda VPN Client, you can initiate a VPN connection with the settings from a configured VPN profile.
Before You Begin
Create a VPN profile as described in How to Create VPN Profiles.
Step 1. Start the Barracuda VPN Client
The Barracuda VPN Client can be started in one of the following ways:
- Click Connect after left-clicking the icon in the system tray.
- Execute rvpn.exe. For more information, see How to Configure Remote VPN.
Step 2. Initiate a VPN Connection
- In the Barracuda VPN Client, select a VPN profile from the Profile list.
- Depending on the profile settings, enter the authentication credentials for server, license, or proxy:
- If the profile is configured for public key authentication, enter your Server Password and License Password credentials.
- If the profile is configured for simple username and password authentication, enter your Username and Password credentials.
If a server password is required, enter your Server Password credentials.
To monitor the progress of your VPN connection, watch the status messages in the client window.
You can close the Barracuda VPN Client window but keep established VPN connections running in the background by clicking Close. You can establish and terminate VPN connections from the Barracuda VPN Client icon in the system tray. For more information, see How to Configure the Barracuda VPN Client for Windows.
Terminate a VPN Connection
To terminate an established VPN connection, click Disconnect in the client window. You can then establish a new VPN connection with a different VPN profile. The Barracuda VPN Client forks a background process that keeps running even if you exit the main client. When you terminate an established VPN connection, this background process is also terminated.

Click Status in the left navidation menu to view properties of an established connection.
The Connection tab displays the connection details:

Exclusive Network Access – If Exclusive Network Access (ENA) has been activated on the VPN server, this check box is automatically selected.
- Secure Routes Section – If secured routes have been assigned to the client by the VPN server, their values will be displayed in the Network and Subnet Mask fields.
The My Account tab shows the authentication method used for the currently established connection and shows a respective status message if the VPN connection is not active. In the same window, the amount of transferred traffic and a graphical representation of the currently used bandwidth is shown.
The Message tab displays the initial welcome message that is configured on the VPN server.
The Data Integrity and Encryption section displays the following details:

As long as an active connection to the VPN server is established (Barracuda Networks authentication only), a Change Server Password link enables you to change your password on the server. Open the configuration dialog, insert a new password, confirm it, and attest authenticity by inserting the current server password.
