Hello, I've recently set-up a Zyxel NSA325 (2 x 1tb drives) for the 1st time in association with a D-Link 635 router. I selected 1 volume across both disks and have completed uploading all my photos/music/video on to the NAS disks. Now I what to ensure the files are secure. I have read somewhere that Routers automatically keep all inbound ports closed and therefore there is no risk of an attact getting past the router from the internet. So I would welcome any advice on how to ensure these files are protected from attack. My thanks in advance, travelbuddy.
