The only thing it does right now is take up space. It doesn't have nearly the features that my Sonicwall does. Yes, I do make heavy use of IPSec VPN and the IDS.
I only bought it for Timemachine, nothing more.
I can't return it and I can't get anyone to buy it (unless I sell it for half of what it is worth)
Well then best sell it. That's what it's currently worth 'used'.
