Getting Started

  • Last updated on

These instructions are an expanded version of the Barracuda NextGen Firewall X-Series Quick Start Guide that was shipped with your appliance. If you have already completed the steps in the Quick Start Guide, go to Step 4.

To get started with your Barracuda NextGen Firewall X-Series, you must complete the activation procedure and integrate the firewall into your existing network. You can also directly replace an existing firewall if your ISP assigns the WAN IP address via DHCP. For all other types of Internet connections, you must first complete activation and basic setup in the existing network. After completing the basic setup wizard, you can evaluate the X-Series Firewall as a firewall, using one of the firewall configuration wizards, or as a remote access gateway, using the Remote Access Gateway wizard.
