NordVPN! Remeber to set it up on your NAS (if you have one). Very happy customer. 24 hour support chat as well. Highly recommended!
Can I ask why you would need to setup on your nas?
I use Windscribe here. I managed to get a voucher on Stack Exchange to discount the cost of the subscription.
Comes with apps for iOS, Android, Windows and Mac to manage the connection and also have it setup on my QNAP NAS for downloading. It also has specific servers for Netflix to overcome location restrictions that, to date, I haven't had any problems with in Netflix detecting that I'm using a VPN (which the standard selections seem to suffer from).
Are there any free VPN setups out there?
I know there are the ones that just give you a different location, but the one I mean is where you can actually remote into your network from a remote location?
