Barracuda Networks Spam Firewall - Deployment and Administration

Deployment

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 Spam Firewall.

Multiple Email Server Environment:

The Barracuda Spam Firewall supports multiple email servers and multiple domains.

Fault Tolerant Barracuda Spam Firewall Environment:

For automatic scalability, redundancy and fault tolerance, you may cluster multiple Barracuda Spam Firewalls.

Multiple Email Server Location Environment:

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

Outbound mode Standard Deployment Configuration:

The standard deployment configuration consists of a single email server and a single Barracuda Spam Firewall Outbound mode. Simply connect the Barracuda Spam Firewall Outbound mode to your network by assigning it a new IP address and changing your mail server's MTA to point to the Barracuda Spam Firewall Outbound mode. Alternatively, you may block all outbound port 25 traffic on your firewall to only allow traffic from the Barracuda Spam Firewall Outbound mode.

The Barracuda Spam Firewall Outbound mode can also support multiple email servers and multiple domains and may be used in environments where there are multiple email server locations. We recommend a Barracuda Spam Firewall Outbound mode for each location that contains an email server.

Administration

Configuration:

Configuration of the Barracuda Spam Firewall is accomplished through a simple Web-based interface that is built into the system. There is no software to install and no CDs or floppies to lose.

The configuration screens are comprehensive and provide for a large amount of customization. This customization is rarely needed because the Barracuda Spam Firewall comes with default settings and self-tuning parameters such that 95% percent of the options never have to be adjusted.

Statistics Reporting:

The Barracuda Spam Firewall's administrative tools feature state-of-the-art, statistical reporting tools that give you a visual edge on spam levels in your network.
