How do you isolate IPv6 clients so that they will not find each other. Is it disabling the Router Advertisement-Service or disabling neighbor advertisement.
Do you want to block them from the router or communicating each other in the same lan? The latter cannot be controlled if it is not wifi.
I want to block them from communicating each other on 2GHz. I have checked the option client isolation for 2.4 but I am not sure if that option works for IPv4 only or both IPv6.
It should work for either since the wifi driver considers only layer 2.
