Proftpd Passive Mode Problem

I'm using proftpd v1.2.10rc1. The proftpd.conf is as follow:

ServerName "FTP Server"
ServerType standalone
DefaultServer on
DefaultTransferMode binary
ServerIdent on "Welcome to FTP Server"
DefaultRoot ~ !users
Port 21

AllowForeignAddress on

MaxLoginAttempts 2
MaxClientsPerHost 2

User nobody
Group nogroup

MaxInstances 10

ExtendedLog /usr/local/var/proftpd/access.log WRITE,READ write
ExtendedLog /usr/local/var/proftpd/auth.log AUTH auth
ScoreboardFile /usr/local/var/proftpd/proftpd

TimeoutLogin 60
TimeoutIdle 120
TimeoutNoTransfer 900

PathDenyFilter "(^|/)[-.]"

UseFtpUsers off
RootLogin off
PersistentPasswd off

AccessGrantMsg "%u is successful to log in"

TransferLog /usr/local/var/proftpd/xferlog
LogFormat default "%h %u %t \"%r\" %s %b"
LogFormat auth "%v [%P] %h %t \"%r\" %s"
LogFormat write "%h %u %t \"%r\" %s %b"

<Global>
Umask 022
RequireValidShell on
DirFakeGroup on
DirFakeUser on
DirFakeMode 0440
AllowRetrieveRestart on
</Global>

I've no configured passive mode and it should use Active Mode now. However, when I use FileZilla that I must select "Passive Mode" to see all files and directory. In addition, if I use "cmd" from Windows, the "ls" command cannot be used to list out files.

What happen and how can I solve it? In fact I would like to use Active Mode.

 

I think it's a firewall problem. If you change your firewall rules then it should work.
