RT-AC68U devices to have seperate DNS?

[Randy BELL]

I have searched the forums and cant quite find what I'm looking for. I am trying to set up a seperate DNS only for my ROKU device and have the rest of the devices on my network have the DNS automatically set by my provider. Is there any way I can do this with the RT-AC68U?

Well, the simplest way would be to leave the router alone and to setup the specific DNS on the ROKU device...

But I recall that ROKU uses Google DNS by default and only if Google DNS is blocked it will use the routers DNS via DHCP - maybe I am wrong...
...not sure you can manually set the DNS (like you cannot on Google's Chromecast).

1. Set DNS server for ROKU on WAN page

2. Set DNS server for others on LAN - DHCP server page (your ISP dns server)

3. Assign a static ip for ROKU manually (ex: 192.168.1.254)

4. add this rule in /jffs/scripts/firewall-start
iptables -t nat -A PREROUTING -s 192.168.1.254 -p udp --dport 53 -j DNAT --to 192.168.1.1
iptables -t nat -A PREROUTING -s 192.168.1.254 -p tcp --dport 53 -j DNAT --to 192.168.1.1

then only ROKU will use WAN page dns.
