Firmware and Configuration 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.

18.1 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.
The following table is a summary. Please note that the internal filename refers to the filename on the
ZyWALL and the external filename refers to the filename not on the ZyWALL, that is, on your computer,
local network or FTP site and so the name (but not the extension) will vary. After uploading new firmware
see the ZyNOS F/W Version field in Menu 24.2.1 - System Maintenance - Information to confirm that
