Resetting the ZyWALL

If you forget your password or cannot access the ZyWALL, you will need to reload the factory-default
configuration file. Uploading this configuration file replaces the current configuration file with the factory-
default configuration file. This means that you will lose all configurations that you had previously and the
speed of the console port will be reset to the default of 9600bps with 8 data bit, no parity, one stop bit and
flow control set to none. The password will be reset to "1234" and the LAN IP address to 192.168.1.1also.
To obtain the default configuration file, download it from the ZyXEL FTP site, unzip it and save it in a
folder. Turn the ZyWALL off and then on to begin a session. When you turn on the ZyWALL again you will
see the initial screen. When you see the message "Press any key to enter Debug Mode within 3 seconds"
press any key to enter debug mode.
To upload the configuration file, do the following:
1. Type atlc after the Enter Debug Mode message.
2. Wait for the Starting XMODEM upload message before activating XMODEM upload on your
terminal.
3. After a successful firmware upload, type atgo to restart the ZyWALL.
The ZyWALL is now reinitialized with a default configuration file including the default password of "1234".
3.4.1 Methods of Restoring Factory-Defaults
You can erase the current configuration and restore factory defaults in three ways:
a. Upload the default configuration file via the console port as described above. See later in
this User's Guide for more information on how to transfer the configuration file to your
ZyWALL using the SMT menus.
b. Use the RESET button on the rear panel of the ZyWALL (see the next section). Use this
method for cases when the password or IP address of the ZyWALL is not known.
c. Use the web configurator to restore defaults (see the web configurator HTML help).
3.4.2 Procedure To Use The Reset Button
Make sure the SYS LED is on (not blinking) before you begin this procedure.
1. Press the RESET button for ten seconds, and then release it. If the SYS LED begins to blink, the
defaults have been restored and the ZyWALL restarts. Otherwise, go to step 2.
2. Turn the ZyWALL off.
3. While pressing the RESET button, turn the ZyWALL on.
4. Continue to hold the RESET button. The SYS LED will begin to blink and flicker very quickly
after about 10 or 15 seconds. This indicates that the defaults have been restored and the ZyWALL is
now restarting.
5. Release the RESET button and wait for the ZyWALL to finish restarting.
