This solution applies to Barracuda SSL VPNs, all firmware versions.
The Barracuda SSL VPN is Java based. The only software prerequisite for a client machine, for most functionality, is to have a version of Java installed.
Exceptions to this are Network Connect and the Server Agent.
The minimum version of Java that the SSL VPN can interact with is Java 1.4, however in order to get access to all features it is recommended to use a minimum of Java 1.5.
