Hello All,

I am having an issue establishing a connection with an server 2003 ftp
server. It is behind a IP Proxy that is natting all traffic to it's private
IP address. I can establish a logon session with the server using command
line ftp, but when I attempt to list the directory or try to put a file it
fails to establish a data connection. Any ideas where to start trouble
shooting. Is the issue because both systems, client and server, are behind
ip proxies?

ftp commands:

Connected to ftp.XXXX.com.
220 Microsoft FTP Service
User (ftp.coopresearch.com:(none)): ftpuser
331 Password required for statestreetftp.
Password:
230 User statestreetftp logged in.
ftp> put test2.txt
200 PORT command successful.

It could be proxy. Try ftp at the local server itself.
if it's working but not via proxy, then make sure required ports is allowed.
in active mode, you need 21(in) and 20 (out).
