CHAPTER 47

Firmware and Configuration File

Maintenance

This chapter tells you how to back up and restore your configuration file as well as upload new

firmware and a new configuration file.

47.1 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.

47.2 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.
