Which step of the Initial Setup Wizard cannot be skipped?

During the Initial Setup Wizard, one of the key requirements is the configuration of the internal network. This step is critical and cannot be bypassed because the internal network setup is essential for the appliance to properly communicate with devices and function within the organization's network infrastructure. The internal network configuration lays the groundwork for the device's integration, ensuring it can effectively monitor, manage, and enforce security policies across the devices within the network.

In contrast, while configuration of IP addresses, external networks, or segments are important for comprehensive setup and application functionality, they can be adjusted or configured later without hindering the core operation of the appliance from the beginning. The internal network configuration is foundational, making it a mandatory step that secures the device’s placement and performance in the network environment from the outset.
