Barracuda NG Firewalls can be evaluated or used for demo purposes in two different ways:
- Transparent Bridging Mode (Inline) - The Barracuda NG Firewall is deployed inline between a computer on your network and the Internet. Since the device acts as a transparent network bridge, no adjustments on the computer or the network are necessary. The Barracuda NG Firewall transparently monitors network traffic between the computer and the Internet.
- Port Monitoring (Parallel) - If your network switch offers port mirroring functionality, you can connect an unused network interface of your Barracuda NG Firewall to the mirroring port of your network switch.
Deploying your Barracuda NG Firewall in Transparent Bridging Mode
When initially connecting to your Barracuda NG Firewall, the unit launches a configuration wizard that guides you through the basic setup. To evaluate or demo the Barracuda NG Firewall, select the Transparent Bridging Evaluation Mode. The setup wizard configures the Barracuda NG Firewall with a transparent network bridge between PORT1 and PORT2 to monitor network traffic between a PC and the corporate network.
Deploying your Barracuda NG Firewall for Port Mirroring
Choose an unused port of your Barracuda NG Firewall to be connected to the mirroring port of your network switch. In the following example, port3 is used for monitoring purposes. Connect to the Command Line Interface of your unit and execute the commands below to enable port3. Then set to Promiscuous mode and enable Port Monitoring mode.
ifconfig port3 up
ifconfig port3 promisc
acpfctrl monitor set port3 on
