I cannot get the firmware uploaded using the commands.

The Web Configurator is the recommended method for uploading firmware. You

only need to use the command line interface if you need to recover the firmware.

See the CLI Reference Guide for how to determine if you need to recover the

firmware and how to recover it.

My packet capture captured less than I wanted or failed.

The packet capture screen's File Size sets a maximum size limit for the total

combined size of all the capture files on the ZyWALL, including any existing

capture files and any new capture files you generate. If you have existing capture

files you may need to set this size larger or delete existing capture files.

The ZyWALL stops the capture and generates the capture file when either the

capture files reach the File Size or the time period specified in the Duration field

My earlier packet capture files are missing.

New capture files overwrite existing files of the same name. Change the File

Suffix field's setting to avoid this.

56.1 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.
