I have entered the Netgear Roter in the IB3 as an exposed host so that all ports are forwarded. I am more flexible and have the option of setting filters and time restrictions better for the KIDS. The TV box is connected directly to the IB3 and is routed via a separate VLAN via the switch. This way I can also have a different IP addressing IB3 192.168.0.0 and Netgear router 192.168.1.0
In any case, my current configuration would not be possible with either the IB3 or the IB5 Pro alone
