: A new driver significantly reduces CPU overhead, a critical fix for users on high-speed fiber connections. Key Features and Innovations

Use an application like Rufus or BalenaEtcher to flash the decompressed .iso file directly onto a USB flash drive (minimum 4GB).

: The target contents form an ISO 9660 standard image file, used for burning onto physical optical media, flashing onto USB sticks, or mounting directly inside virtual machines.

: After installation, the system will reboot. You will then be asked to configure basic network interfaces: assign which network port is your WAN (to the internet) and which is your LAN (to your internal network). This step is critical.

The decompressed ISO is too large for a 700MB CD. Use an 8GB USB flash drive instead.

Missing certificate errors during boot are generally harmless, but extensive missing files can indicate upgrade issues [5.6].

Assign the interface (connected to your internal switch or local computer).

Since the file ends in .iso.gz , you cannot use it directly. Follow these steps:

Upon reboot, the console will detect your physical or virtual network adapters. You will be prompted to: Configure VLANs (optional).

Requires manual effort to configure advanced features compared to turnkey solutions.

: The underlying OS provides enhanced hardware support and improved stability.

It is highly recommended to uninstall all community packages (like pfBlockerNG, Snort, or Suricata) before initiating the upgrade to avoid conflicts.
