z  If the source address is specified with the ftp client source or ftp command, this source address is 
used to communicate with an FTP server. 
z  If the source address is specified with the ftp client source command and then with the ftp 
command, the address specified with the latter one is used to communicate with an FTP server. 
The source address specified with the ftp client source command is valid for all FTP connections and 
the source address specified with the ftp command is valid only for the current FTP connection. 
Follow these steps to establish an IPv4 FTP connection:

address to communicate with the 
FTP server by default.

one, and vice versa.
