Next Orbi Firmware must allow guests to see each other but not access Lan

I agree, this funtionality needs to be functional. A guest network is just that "a guest network". I do not want my guests

to access the main r6400v2 wifi or wired networks. A guest wifi network should be separate. An example of what I'm 

looking to do, have my guest 5g network which will have google chromecast and my mobile cell phone on it. These two

devices need to be able to talk to each other. (mobile cell is the controller for chromecast).

Seems like what needs to happen is the check mark for "Allow guests to see each other and access my local network" needs

to be 2 separate options, 1 for "Allow guests to see each other" and 1 for "Just Internet Access". And maybe another for

"Access to local network", these options should be selectable/unselectable individually.

Another way to think about it, a home network that has devices that do not need access to the entire "home" network.

Think of smart devices (they really only need internet access) (TV, streaming devices, etc.) With these devices being 

easily hackable, it would be best to have them isolated and have further configuration of the access they have to the 

internet and local networks.
