DNS not change

bitten · June 23, 2025, 1:24pm

Hello, I'm using OpenWRT for the first time.

But I'm having a problem with DNS.

The router keeps communicating with 127.0.0.1

I changed it, I made a link but it always comes back.

rather a problem with your customizing...

it's the default, why is it a problem, and what are you trying to achieve ?

root@OpenWrt:~# nslookup google.com
Server:         127.0.0.1
Address:        127.0.0.1:53

trouble is, "option noresolv '1'" until you change it !!! You might as well not have dnsmasq running.

frollic · June 23, 2025, 2:56pm

where is it set ?

proftech · June 23, 2025, 3:25pm

/etc/config/dhcp - under dnsmasq

egc · June 23, 2025, 3:29pm

That is not enabled by default, so either you did this yourself or use e.g. https-dns proxy or another DNS resolver which does that for you.

frollic · June 23, 2025, 3:29pm

That's not the default setting.

You set it, something you installed did it for you, or you're not using an official image.

proftech · June 23, 2025, 3:37pm

hmm... how do i check for the resolv-proxy? I didn't install anything

frollic · June 23, 2025, 3:38pm

if you haven't "installed anything" simply do a reset.

proftech · June 23, 2025, 3:40pm

I didn't want to lose everything

frollic · June 23, 2025, 3:40pm

then you need to figure out what's causing it, we can't do it for you.

bitten · June 23, 2025, 3:45pm

t

It seems to be an enabled setting, but I didn't see anything about it.
I want the DNS to be 1.1.1.1 and 8.8.8.8
As defined above, once added my router works perfectly

frollic · June 23, 2025, 3:47pm

with the default setting your router would have worked perfectly too, assuming your ISP have a sane DNS IP shipped with the DHCP answer, and there's nothing "strange" about your uplink.

proftech · June 23, 2025, 3:55pm

the only thing - i was previously using a snapshot. Maybe the setting carried over. I have never used anything except "official" packages. I experienced this when I first went from a working router to 24.10. The docs say the setting in dhcp takes precedence.

egc · June 23, 2025, 4:02pm

The setting is under Resolv & Host files

These are the default settings.

If things are changed I would recommend to reset to defaults indeed
Oh and perhaps update to the latest stable build 24.10.1

bitten · June 24, 2025, 4:54pm

@egc I will reset from factory, updated to version 24.10.1

Thank you!

egc · June 24, 2025, 5:02pm

Build 24.10.2 is imminent might be up this week
