Why does the "file is reserved" error appear when uploading a configuration file in the setup wizard

Question:
Why does the "file is reserved" error appear when uploading a backup configuration file in the setup wizard?

Answer:
The "file is reserved" error occurs because the uploaded configuration file is a system-reserved filename used internally by Zyxel firewalls for the current configuration. Uploading a file with the same name may cause conflicts with the system's reserved processes.

How to resolve the issue:

1. Rename your configuration file to a unique and different name (e.g., myconfig.conf).
2. Access the setup wizard.
3. Select the "Restore from a file" option.
4. Upload the renamed configuration file.
