Barracuda S
pam & Virus Firewall - Quick Start Guide
The Barracuda Spam & Virus Firewall is a spam and virus filtering appliance that filters
email in front of your email server. It is physically installed on your network and assigned
an IP address as a node on your internal network. It is common for the Barracuda Spam
& Virus Firewall to be installed in the DMZ area of your network or behind a traditional
firewall. The Barracuda Spam & Virus Firewall will filter out spam and viruses in a
comprehensive fashion from your email before it is delivered to your email server.

This guide provides you with setup instructions for the Barracuda Spam & Virus
Firewall. We recommend reading these instructions fully before starting the

Physical Installation
To install the Barracuda Spam & Virus Firewall:

stable location.
2. Connect an Ethernet Cable from your network switch to the Ethernet port on
the back of the Barracuda Spam & Virus Firewall.
3. Connect a Standard VGA Monitor, PS2 Keyboard, and AC power cord to the
Barracuda. Note: Immediately after connecting an AC Power Cord to the
Barracuda, it may power ON for a few seconds and then power OFF. This
is because the Barracuda is designed to automatically return to a
powered ON state in the event of a power outage.
4. Press the POWER button on the front panel to turn the Barracuda on.
