FTP FOLDER ERROR- Operation Timed Out (On XP machine)

[Guest]

I setup an ftp site on a client machine with windows xp pro. The machine has
two nics, one for internal access and one with a static ip pointing to the
dmz zone between our server and firewall. I set up the ftp site and assigned
the external nic's ip as the ftp site address. An outside company controls
our firewall, so we had them point an assigned ip address to the external nic
card and open port 21. The client pc has sp2, so we enabled ftp on the
windows firewall. Internally, we can access it using the extenal nic ip
address and the assigned ip address. However outside of the company, we get
the following error message:
"Windows cannot access this folder. Make sure you have the file name typed
correctly and that you have permission to accesss the folder. Details: The
operation timed out"
Any suggestions as to why this is happening? How do I get around it? What
can be causing this to happen?
Thanks.

A recent WinXP update appears to have changed something in the FTP setup. I
was having problems with FTP uploads on our website. The transfer would
begin, get about a third of the way through and then the transfer speed
would plummet to ridiculously low values like a few bytes/second.

I ran across this suggestion on Yahoo:

Try setting your FTP client to use "passive mode," in which all connection
requests are initiated by the client.

I did that and now uploads are taking place normally.

YMMV
