Hey guys so I am trying to allow my friends to connect to my ftp server (I am hosting it on Ubuntu Server 15.04), so I set the pasv_address in the configuration and the port range in the configuration and router. But it still doesn't work. Here is what filezilla says:
Response: 227 Entering Passive Mode (0,0,0,0,203,228). Command: LIST Error: The data connection could not be established: ECONNREFUSED - Connection refused by server Error: Connection timed out Error: Failed to retrieve directory listing
And here is my configuration: http://pastebin.com/j1ZyK7K8
