ZyXEL Communications ZyWALL 300 User Manual

ZyWALL USG 300 User’s Guide

This chapter covers how to use the ZyWALL’s File Manager screens to handle the 
ZyWALL’s configuration, firmware and shell script files.

The File Manager screens allow you to store multiple configuration files and shell script files.

When you apply a configuration file, the ZyWALL uses the factory default settings for any 
features that the configuration file does not include. Shell scripts are files of commands that 
you can store on the ZyWALL and run when you need them. When you run a shell script, the 
ZyWALL only applies the commands that it contains. Other settings do not change.

You can edit configuration files or shell scripts in a text editor and upload them to the 
ZyWALL. Configuration files use a .conf extension and shell scripts use a .zysh extension.

 These files have the same syntax, which is also identical to the way you run CLI commands 
manually. An example is shown below.
