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.
23.3 File Maintenance Over WAN
TFTP, FTP and Telnet over the WAN will not work when:
1 The firewall is active (turn the firewall off or create a firewall rule to allow access from
the WAN).
2 You have disabled Telnet service in menu 24.11.
3
You have applied a filter in menu 3.1 (LAN) or in menu 11.5 (WAN) to block Telnet
service.
4
The IP you entered in the Secured Client IP field in menu 24.11 does not match the
client IP. If it does not match, the device will disconnect the Telnet session immediately.
