The webpage at
http://www.endian.com/fileadmin/documentation/efw-admin-guide/en/efw.system.backup.html says:
The button Factory defaults allows you to reset the configuration of your Endian Firewall to factory defaults. In fact a backup which has been created on first boot will be restored if you do this.
So, can we run this backup process after changing one or two things to create our own set of Factory Defaults?
Basically, there is one or two options we always want to set before creating a new "factory default" and giving the box to the users. Then if the users select to reset to factory defaults, they get our base install.
Thanks,
James
