In a technical sense, there isn't much they can do. They could port scan within your local network from inside your Z3 gateway but it is pretty unlikely. They'll really only be able to see what the Meraki Dashboard shows which is stuff like what IP it received from your router, the outside IP of your router, DNS servers it provides and that's pretty much it. It'll show them data like connection latency as well, so if you saturate your downstream/upstream they'll see something that corresponds. So, if you're afraid of what data they get, it isn't much, but there is some they get to help them monitor/troubleshoot.       http://mywifeixt.net ... View more
