there is a problem if I want to connect to a ftp server that ONLY supports active mode connections.
This is the FileZilla client output:
13:58:31 Status: Connecting to ftp-01.eurorscg.de through proxy

I have enabled Active-Mode in Transfer-Settings but FileZilla still sends the PASV command to the server to obtain the directory listing. That is where it stops.
Since I don't have access to the server and can't change anything on the server side it would be nice if you can have a look at this issue.
And the problem is not in my network configuration, because ws_ftp manages to connect to that server in active mode without any problems.
I even can reproduce the problem with a simple linux ftp command line client outside of our firewall. As soon as I send the PASV command to the server, it stops responding. Without the PASV command, the connection works fine.
