OpenDNS doesn't work for me

Hi,

 

I struggle setting up OpenDNS on my secondary router, but getting the 'oops' page when testing.

The setup right now is:

Spectrum IPS -> Gryphon (main router) -> Netgear WNR2000v5 (secondary router, separate network for kids)

This is the output I'm getting running those 3 commands in mac console:

Nikolays-MacBook-Pro:my-app nik$ nslookup -type=txt debug.opendns.com.
Server:		192.168.2.1
Address:	192.168.2.1#53

Non-authoritative answer:
*** Can't find debug.opendns.com.: No answer

	retry = 2048
	expire = 1048576
	minimum = 2560

Nikolays-MacBook-Pro:my-app nik$ nslookup -type=txt which.opendns.com. 208.67.220.220

Is there any idea why this is happening?

 

Thanks!

Nik

  This is because you are not using OpenDNS now, i.e. your DNS queries do not go to OpenDNS, but to a different DNS service.

  Thank you, rotblitz!

  So even though I point DNS on the secondary router to openDNS, it still doesn't work? Is this because primary router takes over DNS for the secondary and uses ISP dns?

  I have this as DNS servers for the secondary router.

  208.67.222.222

  208.67.220.220

  208.67.222.220

  Can you think of what I'm missing? Is it at all possible to have different DNS servers on a secondary router?

   

  Thank you,

  Nik

  This all depends on how your routers are connected. I cannot know how this is and what you mean by primary and secondary router. Also the router mode is important, NAT or bridged. My idea would be to experiment with different configurations to see which one works.

  By secondary router I mean a router that is plugged into a LAN port of the primary router (primary is plugged into modem). Secondary router doesn't extend wifi network of the first router, but creates a separate wifi network. I want adults to stay on the network of the first router and kids be on the second. Both networks work fine, except I want to drive traffic from the second network through OpenDNS. Can you provide a link to resources where I can read more about NAT/bridged config?

  Thanks for the explanation. What you did should work, but doesn’t. I don’t know why. Something prevents the DNS traffic to go to OpenDNS from the secondary router.

  Regarding NAT/bridged, an Internet search should help.
