[Enabling VLAN broke my NAS? How can I disable it?]

Hey Everyone

 

So I was stumbling around in the dark trying to enable VLAN support to get an IP Camera connected to a dumb switch [al la SpaceInvaders video for a CCTV system] to appear and I'm guessing I misconfigured it royally as I cannot connect to my NAS through the network anywhere and I have no idea how to disable it via the terminal on the box.

 

Can anyone help me untangle this mess as I have been trying for about a year to build this stupid CCTV system for my parents as they're getting on in years...

 

Cheers

I would love this as I back large video files for editing on my NAS
