The "Additional DNSMasq Options" is an optional setting in the tab: Services > Services.

DHCP Options

  • DHCP-Authoritative should be set when DD-WRT is the only DHCP server on its network segment (the most common setup). When authoritative, the DHCP server will immediately assign new addresses to clients that try to register using IPs from another network (rather than letting their previous lease time run out). (forum thread)

DNS Options

  • Forced DNS redirection redirects all DNS requests on port 53 to DD-WRT's internal DNSmasq server, even if those requests were pointed directly at an external DNS server. Note that, as discussed in the forum thread, savvy users might still be able to communicate with external DNS servers on non-53 ports. (forum thread)

This redirects the stupid babylon search engine to google.
