By enabling this option their DNS lookup will get always get redirected if they are going over port 53. A client on your network can still configure their own DNS server for lookups to bypass the dnsmasq server on your router. When enabled, anything going out to UDP port 53 is redirected to Dnsmasq. Intercept DNS Port (UDP 53): This option may be helpful when used with OpenDNS for parental control. If the server stops responding then Dnsmasq sends out another request and reassigns the primary server. The first server to reply back becomes the primary DNS server. Upon startup Dnsmasq sends a query to all configured DNS servers in /etc/resolv.dnsmasq. I turn this off since my ISP's DNS server can be slow at peak hours. Use Received DNS With Static DNS: This option configures dnsmasq to use your ISP's DNS server in addition to any Static DNS entries you have specified. Use Internal Caching DNS Forwarder: This option enables the dnsmasq DNS lookup caching. Now we are going to enable dnsmasq and add some options. If you sign up for an account at you will also get the benefit of network shortcuts, stat gathering, and website blocking.īut you do not need an account to use the OpenDNS servers.Īnd in the LAN section, under Static DNS, enter the OpenDNS servers IP addresses. OpenDNS by default protects you from phising sites and auto-corrects mistyped urls. OpenDNS servers are faster and have a larger DNS lookup cache than your typical ISP provider DNS server. I decided to share my research and write this simple howto if you want to enable and use dnsmasq within Tomato.įirst consider using OpenDNS as your dns provider. By default Dnsmasq is configured to only cache 150 DNS lookups a very small number that can easily be exceeded by a typical home network. Tomato includes Dnsmasq, a lightweight DNS forwarder and DHCP server. Here googled optimizing DNS on Tomato and found this article.
