A digital parasite that used the pfSense serial number as its anchor, its true name.

The safest way to edit config.xml is to back it up via the web interface ( Diagnostics > Backup & Restore ), download the file to your computer, edit it there, and then restore the modified configuration.

If your official Netgate appliance loses its hardware identity string after a corrupt upgrade, contact Netgate Support immediately with a photo of your physical chassis barcode to restore your software access.
