Exactly.  We changed our firewall, and now some clients can't connect.  I
need to know why.  Certainly, it's the firewall that made the difference,
nevertheless, the firewall _does_ allow passive connections in some cases.
What I see is that TidFTP doesn't work, but at least one other ftp client
does work.

Here's what filezilla is telling me. I think this is saying that our server
is saying please connect on the following ip and port, right? That's the
correct IP number.

Command: PASV

Response: 227 Entering Passive Mode (67,105,137,203,7,208)

Command: LIST

Error: Transfer channel can't be opened. Reason: A connection attempt failed
because the connected party did not properly respond after a period of time,
or established connection failed because connected host has failed to
respond.

Error: Could not retrieve directory listing
