DNSMasq using alternative DNS-Servers
From DD-WRT Wiki
You want to use an alternative DNS-Servers with DNSMasq and not the DNS-Servers assigned to your router from your provider? (And you also don't want to change your DHCP-Settings in your router to push the alternative DNS-Servers to your clients because you also use many static IP-addresses.)
Precondition: Every computer in your network use your router as DNS-Server. (Computer who do not use your router as DNS-Server will not be affected by this change.)
There can be many purposes why you want to use other DNS-Server (and not the DNS-Servers of your provider)
- You provider hijacks every DNS-request which can not be resolved and redirects it directly to his own search page on his web servers (e.g. the German provider T-Online)
- other reasons...
- Go to the Commands tab under Administration.
- In the Commands box paste the following:
echo "nameserver 18.104.22.168 nameserver 22.214.171.124" > /tmp/resolv.dnsmasq sleep 1 killall -HUP dnsmasq
- Click Save Firewall (note: your WAN interface will be restarted)
And of course you can replace the listed DNS-Servers by your own desired servers. If necessary, you can find a few open DNS-Servers at  (Sorry - but it is only available in German language).
After that step you just have to restart your router (or even a re-connect to your internet provider is enough).
