I am using apache ftp server 1.05 as server, commons-net jar as accessing server from a remote client.
I have defined inbound/outbound rules for port 2121, 21 on my server site which FTP server is installed. Then I run my program but it throws above exception in ftp side.

[ INFO] 2015-06-03 17:21:00,901 [siguard] [141.29.18.175] SENT: 425 Can't open data connection. Then I changed ftpd-typical. xml. I have added passive ports definition there. Then I also defined inbound/outbound rules for these ports on firewall. Then I can list files. But I can not upload/download files. I think Server is also using other ports except ones defined in xml. I am sending logs
