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





Multiple Email Server Environment
The Barracuda Spam & Virus Firewall supports multiple email servers and multiple domains.





Fault Tolerant Barracuda Spam & Virus Firewall Environment
For automatic scalability, redundancy and fault tolerance, you may cluster multiple Barracuda Spam & Virus Firewalls.





Multiple Email Server Location Environment
The Barracuda Spam & Virus Firewall can also be used in environments where there are multiple email server locations. For optimal performance, a Barracuda Spam & Virus Firewall should be placed in each location that contains an email server. This remote clustering capability can greatly simplify control and administration.
