Configuring an SSL Certificate
In order to only allow secured connections when accessing the Web administration interface,
you need to supply a digital SSL certificate which will be stored on the Barracuda SSL VPN.
This certificate is used as part of the connection process between client and server (in this
case, a browser and the Web administration interface on the Barracuda SSL VPN). The
certificate contains the server name, the trusted certificate authority, and the server’s public
encryption key.
The SSL certificate which you supply may be either private or trusted. A private, or self-
signed, certificate provides strong encryption without the cost of purchasing a certificate
from a trusted certificate authority (CA). However, the client Web browser will be unable to
verify the authenticity of the certificate and a warning will be sent about the unverified
certificate. To avoid this warning, download the Private Root Certificate and import it into
each browser that accesses the Barracuda SSL VPN Web administration interface.
You may also use the default pre-loaded Barracuda Networks certificate. The client Web
browser will display a warning because the hostname of this certificate is
"barracuda.barracudanetworks.com" and it is not a trusted certificate. Because of this, access
to the Web administration interface using the default certificate may be less secure.
A trusted certificate is a certificate signed by a trusted certificate authority (CA). The benefit
of this certificate type is that the signed certificate is recognized by the browser as trusted,
thus preventing the need for manual download of the Private Root Certificate.
Viewing System Tasks
Go to the Advanced > Task Manager page to see a list of tasks that are in the process of
being performed and any errors encountered when performing these tasks. Some of these
background tasks include firmware download and configuration restoration.
Backing up and Restoring Your System Configuration
Back up and restore the configuration of your Barracuda SSL VPN using the Advanced >
Backup page. You should back up your system on a regular basis in case you need to restore
this information on a replacement Barracuda SSL VPN or in the event your current system
data becomes corrupt.
If you are restoring a backup file on a new Barracuda SSL VPN that is not configured, you
need to assign your new system an IP address and DNS information on the Basic > IP
Configuration page.
The following information is not included in the backup file:
• System password
• System IP information
• DNS information
