transfers the configuration file on the ZyWALL to your computer and renames it “config.rom.” 
See earlier in this chapter for more information on filename conventions. 

Step 7.  Enter “quit” to exit the ftp prompt. 

More commands (found in GUI-based FTP clients) are listed earlier in this chapter. 

Refer to section 33.3.5 to read about configurations that disallow TFTP and FTP over WAN. 

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.
