I've got a LAMP server at home. When I want to acces FTP on my server, it all goes fine, but when I want to enter my server on a remote (10 cm away) computer, I got a 425 Security: Bad IP connecting error, aswell in my browser (ftp://evirorsknights.8s.nl) as in a FTP programm (ASCII on, Passive on, both off, combinations). It recognizes my Username and Password all fine, but it can't load the content of the directory...

What is going wrong?

Thanks in advance
