Resetting The Zywall - ZyXEL Communications ZyWALL USG 300 User Manual

I cannot download the ZyWALL's firmware package.
The ZyWALL's firmware package cannot go through the ZyWALL when you enable
the anti-virus Destroy compressed files that could not be decompressed
option. The ZyWALL classifies the firmware package as not being able to be
decompressed and deletes it.
You can upload the firmware package to the ZyWALL with the option enabled, so
you only need to clear the Destroy compressed files that could not be
decompressed option while you download the firmware package. See
30.2.1 on page 501
could not be decompressed option.
I changed the LAN IP address and can no longer access the Internet.
The ZyWALL automatically updates address objects based on an interface's IP
address, subnet, or gateway if the interface's IP address settings change.
However, you need to manually edit any address objects for your LAN that are not
based on the interface.

52.1 Resetting the ZyWALL

If you cannot access the ZyWALL by any method, try restarting it by turning the
power off and then on again. If you still cannot access the ZyWALL by any method
or you forget the administrator password(s), you can reset the ZyWALL to its
factory-default settings. Any configuration files or shell scripts that you saved on
the ZyWALL should still be available afterwards.
Use the following procedure to reset the ZyWALL to its factory-default settings.
This overwrites the settings in the startup-config.conf file with the settings in the
system-default.conf file.
Note: This procedure removes the current configuration.
If you want to reboot the device without changing the current configuration, see
Chapter 51 on page
Make sure the SYS LED is on and not blinking.
