Chapter 10
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.
10.1 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 name of zywall.rom or
similar. Once you have customized the ZyWALL's setting, they can be saved back to your computer under
a filename of your choosing. Choose something meaningful, e.g., “zywall.cfg”.
The ZyNOS firmware file (sometimes referred to as the ras file) is the file that contains the ZyXEL
Network Operating System firmware and usually is the router model name with a *.bin extension, e.g.,
zywall.bin.
With serial (XMODEM) transfer, the filenames on the computer are your choice. With many ftp and tftp
clients, they are similar to those seen next.
ftp> put zywall .bin ras
This is a sample ftp session showing the transfer of the computer file " zywall.bin" to the ZyWALL.
ftp> get rom-0 zywall .cfg
This is a sample ftp session saving the current configuration to the computer file zywall.cfg.
If your [t]ftp client does not allow you 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, i.e., on your workstation,
local network or ftp site and so the name (but not the extension) will vary. The AT command is the
command you enter after you press
y when prompted in the SMT menu to go into debug mode. After
uploading new firmware see the ZyNOS F/W Version field in Menu 24.2.1 — System Maintenance —
Information to confirm that you have uploaded the correct firmware version.
