DSM-G600, DNS-3xx and NSA-220 Hack Forum

Hi,

First of all, thanks for a great forum!

I'm a new owner of a DNS-323 and have used the instructions on how to enable FTP behind a router by following the instructions found here:
http://dns323.kood.org/howto:open_ports_ftpd
I have added the following line to my fun_plug (modified with the correct IP-address of course)
pure-ftpd -P <your_public_ip_address> -p 65501:65510 -S ,21 -B -C 3 -I 2 -E -T 100:100

The FTP works fine, but when I add a user via the admin user interface and set that user to for example the path Volume_1/FTP/Users/NewUser, the user can step up from that folder to all other folders (like Volume_1/ReallyPrivateStuff), even up to the root above Volume_1. Have I missed some crucial configuration parameter?

Thanks
Deas
