ZyNOS (ZyXEL Network Operating System sometimes referred to as the “ras” file) is the system firmware and 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.

FTP Restrictions

FTP will not work when:

1The firewall is active (turn the firewall off or create a firewall rule to allow access from the WAN).

2You have disabled the FTP service in the Remote Management screen.

3The IP you entered in the Secured Client IP field does not match the client IP. If it does not match, the device will disallow the FTP session.

21.1.3Before You Begin

•Ensure you have either created a firewall rule to allow access from the WAN or turned the firewall off, otherwise the FTP will not function.

•Make sure the FTP service has not been disabled in the Remote Management screen.
