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:
1 You have disabled the FTP service in the Remote Management screen.
2 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.
22.1.2 Before You Begin
Make sure the FTP service has not been disabled in the Remote Management screen.
22.1.3 Firmware and Configuration Files Examples
This section contains examples about managing configuration files and uploading firmware to
your ZyXEL Device.
Using FTP to Restore Configuration
This example shows you how to restore a previously saved configuration. Note that this
function erases the current configuration before restoring a previous back up configuration;
please do not attempt to restore unless you have a backup configuration file stored on disk.
FTP is the preferred method for restoring your current computer configuration to your device
since FTP is faster. Please note that you must wait for the system to automatically restart after
the file transfer is complete.
