Plesk 12.x / Linux :: Firewall Enabled - FTP Stopped Working In Passive Mode

I am running Plesk 12 . Centos 6.5

I have Plesk Firewall Installed.

After the Plesk Firewall was enabled the FTP Stopped working in passive Mode.

I searched the net and found the following :

Code:

/etc/sysconfig/iptables-config and change the line with IPTABLES_MODULES to: IPTABLES_MODULES="ip_conntrack_ftp"

It started working.

I changed the default FTP port from proftpd.conf

Code:
port 2392
and /etc/services

Code:
ftp 2392/tcp
ftp 2392/udp fsp fspd

I allowed the new port in Plesk Firewall in Incoming connection and disabled port 21

Now I am not able to connect to the ftp, I get the following error. Have I missed anything ?

Code:

Response:257 "/" is the current directory
Command:TYPE I
Response:200 Type set to I
Command:PASV
Response:227 Entering Passive Mode (85,25,51,34,216,46).
