Title says it all. Qnap V3.5 firmware has added these features. Actually disk encryption has been around but they added the ability to encrypt an external disk (usb or eSata).
I succeeded building freeradius on my Duo in spring `11, but can't get my head around that addon building process. See: viewtopic.php?f=61&t=39213
Astonishingly you can now even install freeradius from the debian repositories. Back then, the dependencies were broken between the readynas.com repositories and the original debian sarge repositories for certain packages.
