Title: Setup unblock US DNS
Post by: Hoju on July 15, 2014, 01:01:13 am: Hi I am having trouble setting up an alternate DNS (Unblock US). I enter the DNS numbers using the web address for the almond+ but it is not recognizing the setting. Any help would be appreciated.

Verizon hijacks bad DNS lookups for their advertising page, and you have to override the DNS servers to disable this "feature". When I do this, the old DNS servers still seem to be honored, and the ad page is still served for bad DNS lookups.

I have traced the problem to /tmp/resolv.conf.auto which seems to APPEND the "Use custom DNS servers" to the existing ones provided by the DHCP lease, rather than replace them. My /tmp/resolv.conf.auto file winds up with 4 DNS servers, the two provided by the DHCP lease, and the my two custom overrides.

I'm not sure if I'm doing something wrong, or if the "custom DNS" functionality isn't working quite right, and appending rather than replacing dns server entries.

Anyone savvy enough to provide a more concrete way to explicitly force the custom DNS servers to be used instead of in addition to the ISP provided DNS servers?

I'm going to try fiddling with some of the resolv.conf files.

If I let the interface reset, I had to go in and remove the VZ provided entries from /tmp/resolv.conf.auto.

Thanks for this. I looked through the OpenWRT pages but didn't find this-- it was well buried.

Feature request: I think that this checkbox should be added to the Securifi Web interface, since otherwise adding DNS servers there won't work the way people expect.
