    Hi All,

    I'm trying to bypass my ISPs DNS server and use OpenDNS instead. I see ways to alter the internal (LAN) DNS, and add Dynamic DNS, but I just want to change my WAN DNS. (After BrightHouse patched their DNS servers, it takes about 15 seconds to resolve a URL!!!)

    I thought this might have something to do with DNSMasq, but it looks like that only applies to internal (LAN) DNS setups.

    Go to BASIC | Network.

    Put the OpenDNS IP addresses in the Static DNS entries under LAN.

    Optionally, in ADVANCED | DHCP / DNS you can select whether or not to add the ISP DNS values to the static ones by means of the "Use Received DNS With Static DNS" check box.

    It's the Static DNS fields under the WAN / Internet section of Basic -> Network.

    You can manually put the OpenDNS servers in there. Or if you have an OpenDNS account and add it as a service under Basic -> DDNS, you can tick the "Use as DNS" box and the firmware will add them for you.

    Also if you tick the "Use Received DNS With Static DNS" box under Advanced -> DHCP / DNS, the firmware will add the first ISP provided DNS server as a 3rd DNS server or not if unticked.

    Additionally you can specify "strict-order" Dnsmasq Custom Configuration which will change the behavior from going with the first responding DNS server to strictly going with server 1, then 2 and 3 (if present) unless they don't respond.

    Thanks, Guys! The Basic->Network Static DNS fields looked like what I was looking for, but I wasn't sure.

    As a side note (or a plug for OpenDNS), I added their servers to the DNS list on my MacBook, and it really sped things along! Can't wait to use them for the whole network.

    Yeah. Everything worked perfectly. Thanks again.

    It would make more sense to me if the Static DNS entries were under the WAN section instead of the LAN section (as they currently are). Putting them under the LAN heading made me think it had to do with static DHCP addresses for some reason.

    Maybe that's why I'm still a "Network Newbie." :)
