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: 
The firewall is active (turn the firewall off or create a firewall rule to allow access from 
the WAN).
You have disabled the FTP service in the Remote Management screen. 
The 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.
21.1.3  Before 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.
