So the FTP daemon seems running
What FTP client do you use for trying to login you?
Do you use http://net2ftp.com for tests?
If so, with your settings you must add the IP mask: "178.63.69." in the filter field
In the FTP access menu, do you have user account names which are listed .
Finally, what are the messages in the FTP log?
See you later... ;)
