ZyWALL USG 50 User’s Guide

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 
expires.

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.

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 

.

Make sure the SYS LED is on and not blinking.
