the ZyXEL Device's settings, they can be saved back to your computer under a
filename of your choosing.
The system firmware has a "bin" filename extension. Find this firmware at
www.zyxel.com. 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 ZyXEL Device.
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 ZyXEL Device 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 ZyXEL Device and the external filename refers to the filename
not on the ZyXEL Device, that is, on your computer, local network or FTP site and
so the name (but not the extension) may vary. After uploading new firmware, see
the Status screen to confirm that you have uploaded the correct firmware
version.
