Firmware and Configuration File
This chapter tells you how to back up and restore your configuration file as well as upload new
firmware and a new configuration file.

40.1 Introduction

Use the instructions in this chapter to change the ZyWALL's configuration file or upgrade its
firmware. After you configure your ZyWALL, you can backup the configuration file to a
computer. That way if you later misconfigure the ZyWALL, you can upload the backed up
configuration file to return to your previous settings. You can alternately upload the factory
default configuration file if you want to return the ZyWALL to the original default settings.
The firmware determines the ZyWALL's available features and functionality. You can
download new firmware releases from your nearest ZyXEL FTP site to use to upgrade your
ZyWALL's performance.

40.2 Filename Conventions

The configuration file (often called the romfile or rom-0) contains the factory default settings
in the menus such as password, DHCP Setup, TCP/IP Setup, etc. It arrives from ZyXEL with a
"rom" filename extension. Once you have customized the ZyWALL's settings, they can be
saved back to your computer under a filename of your choosing.
ZyNOS (ZyXEL Network Operating System sometimes referred to as the "ras" file) is the
system firmware and has a "bin" filename extension. With many FTP and TFTP clients, the
filenames are similar to those seen next.
ftp> put firmware.bin ras
This is a sample FTP session showing the transfer of the computer file " firmware.bin" to the
ZyWALL.
ftp> get rom-0 config.cfg
This is a sample FTP session saving the current configuration to the computer file
"config.cfg".
If your (T)FTP client does not allow you to have a destination filename different than the
source, you will need to rename them as the ZyWALL only recognizes "rom-0" and "ras". Be
sure you keep unaltered copies of both files for later use.
