Most firewalls allow FTP traffic to pass by inspecting the contents of the control connection to determine which port the client or server is asking to have opened for the data connection, and then unblocking that port. With SSL enabled, the firewall can't do that and so your data connection is blocked. Common problem, has happened to me. The solution is what Alexander recommended-- turn off SSL for the FTP control connection. Of course, then your password is sent in the clear.
