I read almost all topics about my problem and some of the problems are still unresolved.
I have RB4011 and multiple VLANs in my home network. Network was split to VLANs for better security management. There is VLAN for guest, IoT, Office and Home devices (laptops, smartphones). My SmartTV is in one of IoT VLAN and Smartphone is in Home VLAN. Connecting via direct IP entering works great but there is problem with discovery SmartTV by applications like YouTube, Netflix or DLNA. I have much more problems but some of them was resolved by read topic where mdns-repeater was recommended, now I have one in my raspberryPi (which is connected to required VLANs). Now the biggest problem is how to enable discovery by YouTube and Netflix applications?
