After you see a “restore configuration successful” screen, you must then wait one minute
before logging into the ZyXEL Device again.
Figure 174
Configuration Upload Successful
The ZyXEL Device automatically restarts in this time causing a temporary network
disconnect. In some operating systems, you may see the following icon on your desktop.

Network Temporarily Disconnected
If you uploaded the default configuration file you may need to change the IP address of your
computer to be in the same subnet as that of the default device IP address (192.168.1.1). See
Appendix C on page 341
for details on how to set up your computer’s IP address.
If the upload was not successful, the following screen will appear. Click

Using FTP or TFTP to Back Up Configuration
This section covers how to use FTP or TFTP to save your device’s configuration file to your
computer.
25.7.1
Using the FTP Commands to Back Up Configuration
1
Launch the FTP client on your computer.
2
Enter “
open
”, followed by a space and the IP address of your ZyXEL Device.
3
Press
[ENTER]
when prompted for a username.
4
Enter your password as requested (the default is “1234”).
5
Enter “
bin
” to set transfer mode to binary.
6
Use “
get
” to transfer files from the ZyXEL Device to the computer, for example, “
get
rom-0 config.rom
” transfers the configuration file on the ZyXEL Device to your
computer and renames it “
config.rom
”. See earlier in this chapter for more information
on filename conventions.
7
Enter “
quit
” to exit the ftp prompt.

Configuration Backup Using GUI-based FTP Clients
The following table describes some of the commands that you may see in GUI-based FTP
clients.
25.7.4
Backup Configuration Using TFTP
The ZyXEL Device supports the up/downloading of the firmware and the configuration file
using TFTP (Trivial File Transfer Protocol) over LAN. Although TFTP should work over
WAN as well, it is not recommended.
To use TFTP, your computer must have both telnet and TFTP clients. To backup the
configuration file, follow the procedure shown next.
1
Use telnet from your computer to connect to the ZyXEL Device and log in. Because
TFTP does not have any security checks, the ZyXEL Device records the IP address of the
telnet client and accepts TFTP requests only from this address.
2
Enter command “
sys stdio 0
” to disable the management idle timeout, so the TFTP
transfer will not be interrupted. Enter command “
sys stdio 5”
to restore the five-
minute management idle timeout (default) when the file transfer is complete.
3
Launch the TFTP client on your computer and connect to the ZyXEL Device. Set the
transfer mode to binary before starting data transfer.
4
Use the TFTP client (see the example below) to transfer files between the ZyXEL Device
and the computer. The file name for the configuration file is “
rom-0
” (rom-zero, not
capital o).
Note that the telnet connection must be active before and during the TFTP transfer. For details
on TFTP commands (see following example), please consult the documentation of your TFTP
client program. For UNIX, use “
get
” to transfer from the ZyXEL Device to the computer and
“binary” to set binary transfer mode.
Table 121
General Commands for GUI-based FTP Clients
COMMAND
DESCRIPTION
Host Address
Enter the address of the host server.
Login Type
Anonymous.
This is when a user I.D. and password is automatically supplied to the
server for anonymous access.
Anonymous logins will work only if your ISP
or service administrator has enabled this option.
Normal.
The server requires a unique User ID and Password to login.
Transfer Type
Transfer files in either ASCII (plain text format) or in binary mode.
Initial Remote Directory
Specify the default remote directory (path).
Initial Local Directory
Specify the default local directory (path).

25.7.5
TFTP Command Configuration Backup Example
The following is an example TFTP command:
tftp [-i] host get rom-0 config.rom
where “
i
” specifies binary image transfer mode (use this mode when transferring binary files),
“
host
” is the ZyXEL Device IP address, “
get
” transfers the file source on the ZyXEL Device
(
rom-0
, name of the configuration file on the ZyXEL Device) to the file destination on the
computer and renames it config.rom.
25.7.6
Configuration Backup Using GUI-based TFTP Clients
The following table describes some of the fields that you may see in GUI-based TFTP clients.
Refer to
Section 25.3 on page 302
to read about configurations that disallow TFTP and FTP
over WAN.
25.8
Using FTP or TFTP to Restore Configuration
This section 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.
Table 122
General Commands for GUI-based TFTP Clients
COMMAND
DESCRIPTION
Host
Enter the IP address of the ZyXEL Device. 192.168.1.1 is the ZyXEL Device’s default IP
address when shipped.
Send/Fetch
Use “Send” to upload the file to the ZyXEL Device and “Fetch” to back up the file on your
computer.
Local File
Enter the path and name of the firmware file (*.bin extension) or configuration file (*.rom
extension) on your computer.
Remote File
This is the filename on the ZyXEL Device. The filename for the firmware is “ras” and for
the configuration file, is “rom-0”.
Binary
Transfer the file in binary mode.
Abort
Stop transfer of the file.
