I have vsftpd setup on my system to act as an FTP server. It works perfectly as an internal connection but it rejects any external connections. I’m using custom port 5602, and it is forwarded on my router. I am trying to connect via a dyndns hostname, but get the same result when trying via direct IP. The error returned from client FileZilla (but also everything other client I have tried, both Linux and Windows) is;

The current vsftpd config file is.
# Example config file /etc/vsftpd.conf
#
# The default compiled in settings are fairly paranoid. This sample file
# loosens things up a bit, to make the ftp daemon more usable.
# Please see vsftpd.conf.5 for all compiled in defaults.
#
# If you do not change anything here you will have a minimum setup for an
# anonymus FTP server.
#
# READ THIS: This example file is NOT an exhaustive list of vsftpd options.
# Please read the vsftpd.conf.5 manual page to get a full idea of vsftpd's
# capabilities.

pasv is currently disabled cause I was getting numerous errors trying to connect with it turned on so was experimenting with it turned off.
