Need option to capture DNS querires and force the router DNS (port 53 intercept)
I have had this feature on other routers where port 53 is captured by the router and then the routers DNS server is used. I use OpenDNS with varous controls and it's too easy for devices to override and go though custom DNS settings bypassing the OpenDNS controls. This is a very simple IP table command. Yes I understand that some network devices/appliances like to use their own DNS configuration (VoIP, IPTV, etc.) but I have yet to find that forcing the DNS to something else breaks them.

Orbi won't do this - you need a fully-featured router on the edge and use Orbi in AP mode.
