C. File Manager FAQ
C01. How can ZyWALL USG 2000 manage multiple configuration files?
From ZyWALL USG 2000 GUI menu File Manager > Configuration File, it allows admin to
save multiple configuration files. Besides, Admin could "manipulate" files, such as to upload,
delete, copy, rename, download the files, and apply a certain file to hot-switching the
configuration without hardware reboot.
C02. What are the configuration files like startup-config.conf,
system-default.conf and lastgood.conf?
1. startup-config.conf: The startup-config.conf is ZyWALL USG 2000 system configuration
file. When ZyWALL USG 2000 is booting, it will use this configuration file for ZyWALL
USG 2000 as system configuration.
2. system-default.conf: The system-default.conf is ZyWALL USG 2000 system default
configuration file. When you press the reset button, ZyWALL USG 2000 will copy
system-default.conf over startup-conf.conf.
3. lastgood.conf: The lastgood.conf is created after ZyWALL USG 2000 successfully applies
startup-config.conf. And ZyWALL USG 2000 will try to apply lastconfig.conf, if ZyWALL
USG 2000 fail to apply startup-config.conf. You can check the GUI menu Maintenance >
Log to check the configuration applied status after booting.
Please note the configuration file downloaded through web GUI is text-based which is
readable and is very useful for administrator to have a quick overview for the detailed
configuration.
C03. Why can't I update firmware?
It's mandatory to have at least 70MB free memory before upgrade firmware. If you still can't
get enough memory to upgrade firmware, you can perform upgrade after system reboot which
frees up the memory.
