Refer to section 18.2.5 to read about configurations that disallow TFTP and FTP over WAN.
18.4.5 TFTP File Upload
The ZyWALL also supports the uploading of firmware files 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 transfer the firmware and 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 the command “sys stdio 0” to disable the console timeout, so the TFTP transfer will not be
interrupted. Enter “command sys stdio 5” to restore the five-minute console 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.
