Upload Configuration File, select Browse to upload a new or previously saved
configuration file from your computer to your ZyWALL/USG. You cannot upload a
configuration file named system-default.conf or lastgood.conf. If you upload
startup-config.conf, it will replace the current configuration and immediately
apply the new settings.

What Could Go Wrong?
If you cannot apply a configuration file and the device shows error message, go to
Monitor > Log to check the [alert] log message and make the correction of the
configuration file. In this example, the [alert] log message shows the configuration
file has an incomplete static DHCP address so that the device can't apply it.
