I tried it again without any success. Now i installed wordpress to see where the files are saved. I is saved at /var/www/wordpress and has a link to /mnt/HD/HD_a2/Nas_Prog/wordpress. I’ll show you the content of the folders.
/var/www/
/var/www/htdocs/
/mnt/HD/HD_a2/Nas_Prog/
At least i put the ftp Folder to /mnt/…/Nas_Prog and did a link from /var/www/ftp to it.
I have access to it over the Browser but after the login in i ever have a white site.
I tried it with the Raspberry Pi and it worked well.
Edit:
After a reboot the Folder under /var/www is deleted itself again.
