 I was given an HG659 a few days ago and have set it up using ADSL. All working well except for DNS. I use OpenDNS DNS servers, so that internet is safe for my kids. A couple of computers on my home network have custom DNS settings to allow adults to bypass the OpenDNS filtering. However for some reason the computers with custom DNS settings still get DNS resolution from OpenDNS and it is blocking sites need/want to access.


Under Internet > Internet Settings > internet_adsl I have ticked "Static DNS" and have entered servers as and


Under Home Network > LAN Interface > DHCP server I have ticked "Gateway acts as the DNS proxy".


 I have tried clearing DNS cache using CCleaner, restarting router, unticking Gateway acts as the DNS proxy, deleting network adapters and adding again, but they still get DNS from OpenDNS.


 Anyone know how to fix this?

Don't know about your specific issue but you can block sites on specific devices in the hg659 ui. It's under parental controls.
Then you could just use your ISPs DNS as normal.

If the computers are using DHCP then it's logical that they'll be using OpenDNS because you have this set in the router.


Set your router's DNS to your ISP's (which is recommended anyway as OpenDNS will result in a significant performance hit on browsing and CDN performance such as video) and then hardcode the OpenDNS DNS servers to the PC's used by the kids.

 Thanks for replies.


 The URL filter on HG659 uses keyword filtering and is not very good, so won't bother with that.


 My ISP is 2Talk and for computers with custom (static) DNS settings I have set primary DNS as (2Talk DNS) and secondary DNS as (Googles Public DNS). However despite this still gets filtered by OpenDNS.


 I also tried changing HG659 DNS servers to 2Talk DNS servers and settings kid's computers to OpenDNS servers, but then kid's computers didn't get filtered by OpenDNS.


 It seems that whatever DNS servers I put in the HG659 overrides any custom/static DNS servers on individual computers.


 Hope this makes sense.

2talk is CGNAT "private IP" for some plans and so unless you pay for a public IP on your connection OpenDNS filtering is unlikely to work.

 Thanks for your post.


 I do have a 2Talk public IP, so that is not the issue. You are correct that "private IPs" do cause problems.


 I had the exact same DNS setup on my previous ADSL router and all worked well. The issue is specifically to do with the HG659. It seems to me that I have configured it correctly. The HG659 would work well if I wasn't wanting different computers on my network to use different DNS servers.


 I am hoping some other Geekzone members out there have an HG659 and can test putting custom/static DNS settings on one of their computers and see if they also find that HG659 DNS servers override DNS settings of computer.
