I'm looking for an easy and affordable solution to setup and (almost forget) WebDAV server with VPN access. This is going into my parents house, so there needs to be a level of simplicity. Basically, the iPhone or iPad will connect to the VPN and allow for WebDAV (file transfers between the storage device and iPhone/iPad). Does anyone make such a standalone device? I know Western Digital makes a network drive that you can access anywhere and provides 'Cloud' like service, however, this data isn't tied into a VPN. Is there an all-in-one solution or would I need to provide a VPN router? Which VPN routers work with iPhone/iPad?
