Barracuda SSL VPN - Quick Start Guide
The Barracuda SSL VPN is a secure remote access appliance that allows you to access
your internal network resources such as files, intranet Web sites and client/server
applications using just a standard Web browser. It is common for the Barracuda SSL
VPN to be installed directly inside your LAN or in a more advanced DMZ configuration.
Getting Started
This guide provides you with setup instructions for the Barracuda SSL VPN. We
recommend reading these instructions fully before starting the setup. To begin
setting up your Barracuda SSL VPN, you will need the following:

location.
2. Connect an Ethernet Cable from your network switch to the Ethernet port on
the back of the Barracuda SSL VPN.
3. Connect a Standard VGA Monitor, PS2 Keyboard, and AC power cord to the
Barracuda SSL VPN. Note: Immediately after connecting an AC Power Cord
to the Barracuda SSL VPN, it may power ON for a few seconds and then
