If I run the test config tool in Filezilla FTP I get the following message
 
	 
	Connecting to probe.filezilla-project.org 
	Connection established, waiting for welcome message. 
	Response: 220 FZ router and firewall tester ready 
	USER FileZilla

	Response: 200 goodbye!

	But when I then try to connect and run a FTP session I get this error  
	 
 
	Status:    Logged in 
	Status:    Retrieving directory listing... 
	Command:    PWD 
	Response:    257 "/" is current directory. 
	Command:    TYPE I 
	Response:    200 Type I ok. 
	Command:    PASV 
	Response:    227 Entering Passive Mode (68,228,203,131,19,137). 
	Command:    LIST 
	Response:    150 Opening data connection. 
	Error:    The data connection could not be established: ECONNREFUSED - Connection refused by server 
	Error:    Connection timed out after 20 seconds of inactivity 
	Error:    Failed to retrieve directory listing 
	Status:    Connection closed by server
 
	 
 
	When I try to connect with my other FTP client I get this message 
	 
 
	Connecting to IP 
	Connected 
	Starting the session 
	Reading remote directory 
	Could not retrieve directory listing 
	Requested action aborted: Cannot access a disposed object. 
	Object name: 'System.Net.Sockets.Socket'.
 
	So I am not sure how to solve this issue during my setup... I am able to use SFTP to connect with no issues on both the internal and external ip addresses 
	I have turned my firewall completely off and tried setting up a DMZ but I dont think this is a firewall issue since I am getting connected.  I am just being refused by the server for a directory listing Any help would be appreciated
