35.3.5 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 ZyWALL will disconnect the Telnet session immediately.
5. You have an SMT console session running.

35.3.6 Backup Configuration Using TFTP

The ZyWALL 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.
Step 1.
Use telnet from your computer to connect to the ZyWALL and log in. Because TFTP does not
have any security checks, the ZyWALL records the IP address of the telnet client and accepts
TFTP requests only from this address.
Step 2. Put the SMT in command interpreter (CI) mode by entering 8 in Menu 24 – System
Maintenance.
Step 3. Enter command "sys stdio 0" to disable the SMT timeout, so the TFTP transfer will not be
interrupted. Enter command "sys stdio 5" to restore the five-minute SMT timeout (default) when
the file transfer is complete.
Step 4. Launch the TFTP client on your computer and connect to the ZyWALL. Set the transfer mode to
binary before starting data transfer.
