1. is this possible to add yazfi guests to native asuswrt conneted clientlist?
2. is this possible to have guest networks on same subnet as my main lan? all i want from yazfi is one-way-access and isolation for iot, nothing else
3. is this known that iot devices that connect instantly pretty much bypass yazfi on router startup until yazfi starts up and forces the clients to reauth? atleast thats what i suspect is happening as during router bootup my iot devices connect to vanilla asus guest network
