Chapter 49 Troubleshooting

49.1 Resetting the ZyWALL

If you cannot access the ZyWALL by any method, try restarting it by disconnecting and reconnecting the power. 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.

"This procedure removes the current configuration.

If you want to reboot the device without changing the current configuration, see Chapter 48 on page 743.

1Make sure the SYS LED is on and not blinking.

2Press the RESET button and hold it until the SYS LED begins to blink. (This usually takes about five seconds.)

3Release the RESET button, and wait for the ZyWALL to restart.

You should be able to access the ZyWALL using the default settings.
