=== Regarding a passive-mode FTP server behind a firewall ===
When the client requests PASV mode, the server responds back with a PORT command, such as, "227 Entering Passive Mode (127,0,0,1,78,52)".  In order for passive mode to work properly, the passive mode response needs to contain the FTP server's PRIVATE IP address.  Your "passive mode settings" window suggests this should be the external/public IP address.  The private IP address assists the firewall's nat proxy in maintaining the connection across network address translation.  Many FTP NAT proxies will drop the 227 passive mode response, if the public IP address is sent in the 227 message.
