34.3.4 GUI-based FTP Clients
The following table describes some of the commands that you may see in GUI-based FTP
clients.
34.3.5 File Maintenance Over WAN
TFTP, FTP and Telnet over the WAN will not work when:
1 The firewall is active (turn the firewall off in menu 21.2 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 ZyXEL Device will disconnect the Telnet session
immediately.
5 You have an SMT console session running.
34.3.6 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.
