You most likely do not have passive mode enabled on the server side. If you use Wireshark or tcpdump, you will see the client attempt to create a new connection on the passive data ports (eg: SYN client:1517 -> server:46623) with no response from the server before failing after two TCP retransmission packets.

To fix this with pure-ftpd, make the following changes.

Edit /etc/pure-ftpd.conf so that it has the following line:
PassivePortRange 30000 50000

Have the firewall accept this port range:
iptables -t filter -I INPUT -p tcp --dport 30000:50000 -j ACCEPT
