Standard Deployment Configuration

The Standard deployment configuration consists of a single email server and a single Barracuda Spam Firewall. Simply connect the Barracuda Spam Firewall to your network by assigning it a new IP address and changing your MX record to point to the Barracuda Spam Firewall. Alternatively, you may also give your email server a new IP address and give the old IP address to the Barracuda Firewall.

Fault Tolerant Barracuda Spam Firewall Environment
For automatic scalability, redundancy and fault tolerance, simply cluster together multiple Barracuda Spam Firewalls.

Multiple Email Server Location Environment
The Barracuda Spam Firewall may be used in environments where there are multiple email server locations. We recommend a Barracuda Spam Firewall for each location that contains a email server. For example if all of your email is in one location on one server, we recommend a single Barracuda Spam Firewall. if you have three email servers in three locations, we recommend using three Barracuda Spam Firewalls.
