    Greetings,

    In the Merlin firmware, into tools/other settings, we have this option:

    "Wan: Use local caching DNS server as system resolver (default: No)"

    Does it mean that, if enabled, the router acts as a DNS proxy (and does not when disabled) ?


    I get consistently better results in DNS Benchmark with this option disabled. Is this tool still reliable ?

    Thank you.

    This setting only influences DNS queries made by the router itself, not any queries coming from clients on the LAN who use the router as their DNS server. If the setting is No, the router will use the WAN DNS servers for any local lookups. If it is set to yes, it will use the router's own dnsmasq DNS server (same as clients use).

    So your DNS Benchmark results shouldn't be influenced by this setting at all.

    I always click for hints, but i couldn't differentiate queries made by the clients from queries made by the router.
