CAUTION: Orbi's Wifi Guest Network does not really isolate guests from main network
I was just playing around around with the Guest Network in Orbi and made a rather disturbing discovery that guest clients don't seem to be separated totally from the main network, in fact can access ...
It sounds like the Orbi forwards multicast IP packets between the guest and main networks, even when the isolation box is selected, but blocks other IP traffic between these zones. I'm just guessing. I would agree this is a bug. I wonder if this was done to support some services that use broadcast or multicast, like DHCP or uPNP? If so, I would like to see configuration options / check boxes to allow or block specific broadcast and multicast traffic from leaking between guest and primary networks.
Even if the Orbi forwards IP multicast between guest and main networks, that doesn't explain why access to the printer and file server are permitted. Hopefully, Netgear will investigate and respond soon.
