I've noticed that some FTP clients will attempt to use traditional active
mode FTP, and when that times out they switch to passive mode.  Active
mode doesn't work through a firewall, so you always need to use passive.  
To get around this in the standard client called "ftp", type "passive" at
the prompt before opening a connection.  I'm sure there are similar
options for other FTP clients.

You may also want to make sure that the FTP server is only using passive
mode.
