We are not using SSL.
We already use 'fixup'. The directory listing works for our other
customers who use the server, just not this particular one.

Are you using FTP w/SSL? If so, you basically have no choice but to use
passive mode. If you can't, you probably will never get FTP w/ SSL to
work.
If you're NOT using FTP w/ SSL and it's just basic FTP, has your
firewall been setup to "fixup" the FTP protocol? Since you're using NAT
your firewall has to recognize the FTP traffic and re-write not just the
packet headers (Source & Destination addresses) but also the internal
data-frames of the FTP packets. FTP is an "old school" protocol that
embeds source & destination addresses in the datagram. Probably a bad
design decision back then, but in 1960-whatever no one envisioned NAT
so.... it only became a problem many years later.
Make sure your firewall is doing "fixup" (cisco terminology, probably
called something else on other products) for FTP.
Good luck.

Our firewall rules block passive mode, so that is not an option.
I am unable to access the URL provided (cannot find the server or
DNS error). We use 192.168.. for our internal network. Isn't this a
non-routable address?

Doug,
This is probably the most common problem in FTP, can not establish
data channel. In this case, the server can not connect to the client
on the ip, port specified. Most of the time this is due to firewalls
blocking the new connections. I would try passive mode.
For more info look at this page:

Subject: [WS_FTP Forum] Directory listing not work
Customer complains that directory listing doesn't work, so can only do a
CD blindly. I have pasted his log below, which shows no response to
LIST. I'm stumped as to why. He is using PRO 8 and connecting to
SERVER 5. None of my other customers have this problem and I can't
reproduce it using PRO 9. Anybody have any ideas?
