Why does ProFTPd stop at Entering Passive Mode on Debian on a Windows Virtualbox? [closed]

I have installed Debian Squeeze on a Windows computer with Oracle Virtualbox. Then I've port forwarded port 21 on the NAT adapter.

In Debian I've run:

apt-get install proftpd

Then I uncommented the PassivePorts so I have the ports 49152 to 49155 available as passive ports. Then I uncommented MasqueradeAddress and set it to 127.0.0.1

Then after trying to Quick Connect in FileZilla I get:

Status: Connecting to 127.0.0.1:21...
Status: Connection established, waiting for welcome message...
Response:   220 FTP Server ready.
Command:    USER webserver

Response:   227 Entering Passive Mode (127,0,0,1,192,3).
Command:    MLSD
Error:  Connection timed out
Error:  Failed to retrieve directory listing

How can this be fixed? It seems that it's something related to the VM, (running on the same machine right now), because all tutorials out there suppose it should work after just running the apt-get.

Solution 1:

You will need to enable PassivePorst in your proftd.conf -

   PassivePorts      35000 40000

Enable the ip_conntrack_ftp module

   modprobe ip_conntrack_ftp 

In your firewall, all the ports related to ftp/passive ftp have to be opened -

 iptables -A INPUT  -p tcp --sport 21 -m state --state ESTABLISHED -j ACCEPT

 iptables -A OUTPUT -p tcp --dport 21 -m state --state NEW,ESTABLISHED -j ACCEPT

 iptables -A INPUT -p tcp --sport 20 -m state --state ESTABLISHED,RELATED -j ACCEPT

 iptables -A OUTPUT -p tcp --dport 20 -m state --state ESTABLISHED -j ACCEPT


 iptables -A INPUT -p tcp --sport 1024: --dport 35000:40000  -m state --state ESTABLISHED -j ACCEPT

 iptables -A OUTPUT -p tcp --sport 1024: --dport 35000:40000  -m state --state ESTABLISHED,RELATED -j ACCEPT
