Can you install a trusted SSL certificate on the NAS?

Ok.. now we're getting somewhere.

I realise I'm about to go a wee bit beyond the scope of this topic, but what if you could be your own CA? Let's look at this from a closed network model. Let's say you've a completely self-contained network, and you want to be able to assure secure and encrypted communication between two points on that network. Currently, using an SSL certificate requires that certificate to be authenticated against a CA *OUTSIDE* that network. Setting aside our tin foil hats, it defeats the purpose of a self-contained network. If you're able to install your own root CA cert and authenticate against your own CA *internally*... does anyone see where I'm going here? Now, you may ask what's the point? Well, I'm looking at setting up an open source SSL VPN to be able to tunnel into my network from outside, as well as encrypt wireless traffice with a certificate. I live in a fairly dense urban area, and the knowledge required to pop my WPA2 is out there, freely available to anyone who knows how to google "backtrack".

If I'm in the wrong area.. and you know where I should be looking, please assist. Sure I can google for hours to find all the information and peice it together, but my brain hurts after a few hours of trying to make sense of all this. I clearly don't have a "beautiful mind".

Thanks folks!
