DNS Firmware Question

[W3Wilkes]

On an old modem router that I used when on an xDSL connection There was a custom modified firmware that would "shotgun" DNS requests to all specified DNS servers and then take the first response. It also had the ability to specify more than 2 DNS servers. Do either the ASUS or Merlin take this approach with the allowed 2 DNS servers?

You can do this in Merlin by using a custom configuration file.

Thanks, but I have issues with some older b/g devices on the 2.4GHz band with Merlin. These devices are just fine on the current ASUS firmware so I can't run Merlin.

 

[ColinTaylor]

Well you did ask whether Merlin could do this so I replied to that question.

And again, thanks. When Merlin comes up to using the current ASUS firmware I'll be going back to Merlin, but until then...

Some Asus firmwares have the ability to do secure DNS called DoT or DNS over TLS. This is good but not what you are asking for.
However, invest in a Raspberry Pi 3, load up Pi-Hole with Unbound and set the Pi-Hole as the DNS server in Asus and it will do just what you asked about.

These Pi devices are just great! I use a Pi with a HiFi Berry DAC as a player running PicorePlayer with my Logitech Media server since Logitech discontinued the squeezebox line of devices.
