FTP over WAN will not work if you have applied a filter in menu 11.5 (WAN) to block Telnet service.

11.4.4 TFTP File Upload

The Prestige also 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 transfer the firmware and the
configuration file, follow the procedure shown next:
Step 1. Use telnet from your computer to connect to the Prestige and log in. Because TFTP does not
have any security checks, the Prestige 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 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 Prestige. Set the transfer mode to
binary before starting data transfer.
