The problem

I installed Adguardhome on openwrt without changing Dnsmasq as default DNS and dhcp server. I just add a firewall's port forward rule to forward client's DNS query to Adguardhome. It's working flawlessly.

I use this entries to forward all local DNS queries to local Dnsmasq

[//]127.0.0.1:53
[/lan/]127.0.0.1:53
[/local/]127.0.0.1:53

And rewrite min cache TTL to 1800.
But I want all the private DNS query keep its original TTL.
Any solution?

Proposed solution

Disable min cache TTL for private DNS if possible.
