Hello !

If the configuration worked before changing the server, you should be able 
to use the normal ftp (not passive mode). In normal mode, the server 
connects to the client for the data channel (directory listings and file 
transfers). It's a client's problem if the DATA connection could not be 
etablished. Its strange that a server firewall would block outgoing 
connections...


In passive mode, the server tells the client which DATA port it will be 
listening. This range of ports must be opened on the server firewall (the 
ftp server generally rotates through a range of ports to avoid connecting 
to a port that's just being closed).
The default port is 200. You will need to open all ports in the range 200 
to ??? (each PORT command will use another port). There is a PORT for each 
file transfered and each directory listed.
