is there's any way to isolate R3 guest wifi from the main local network, make it so guest clients can't use/see my printers, Apple TVs, speakers, shared local folders. I know other DUMAOS routers are able to do it eg. XR1000. I think I'm done with R3 and ordering an ASUS GT AX-11000. I like the UI of DUMAOS 4 but the lack of features like these is pushing me away.
