Hi there,
What domains need to be accessible from the very restricted retro-vlan to access and successfully download updates from windowsupdatesrestored?
At least these:
- windowsupdaterestored.com
- v4.windowsupdaterestored.com

But these are not enough - what more should I allow?

I'm using a Unifi router so I do se blocked ip's, but I have no idea what hosts should match up against ...
