Problem opening data socket with FTP site running on Win2k Server

[PHead2]

I set up an FTP site on windows 2000 server. The server is behind a firewall but the port I'm using for the ftp connection as well as port 20 are forwarded to the server from the firewall, which also provides NAT to my LAN.
I can connect to the ftp site on the LAN no problem.
When connecting from a remote location over the internet, I can logon to the ftp site, but I cannot "open the data socket", and I can;t view the contents of the home directory.


Any ideas?

Hi,

Is your ftp-clent also behind afirewall?
It seems that the server is failing to establish a datachannel back to the client, he will do that to a random chosen port...

So, what other ports need to be forwarded to the server?
I've tried a three different clients, I know one of them wasn't behind a firewall, one was, and I;m not sure about the other, but I always have the same problem...
