Problem logging in from WAN.

Hi.

I have set up the FileZilla server - and need a bit help.... It sometimes works greate inside the LAN, but not always. Also from the WAN it takes a long time to log in and display the files on the FTP-Server. But i got this messages:

It looks lik its going to try anonymous login. And this take a longe time. Is ther a possebility to disable this function ?? I want it to be quick.


I set up the server: Passive Mode settings: Use following IP adress - "My wan adress" - and check the" Dont use external IP for local connections"
In the global settings "listen to ports : 21"


What can I do ??
