Please note that on these routers this does not prevent the router's internal resolver from doing the DNS lookup itself. This isn't usually a problem, but due to recent DNS amplification attacks sometimes lookups have continued after fixing the original problem. To prevent this add a rule blocking DNS *from* the router's WAN IP *to* port 53. This will prevent usage of the router as the LAN's DNS resolver.
