1.1.1.1 not connecting to my city resolver

Aisfkhan · February 2, 2025, 1:32pm

hey guys.

i have discussed it before about cloudflare resolver not connecting to city server although we have Cloudflare dns resolver in our city too.

no matter what if i configure my openwrt router from wan or dhcp and dns it always connect to Marseille,France.

i have a tp link router with stock firmware and also configured 1.1.1.1 on this router too when i connect my devices to tp link router all my dns queries goes through my city dns server but when i connect to openwrt all the queries goes through Marseille france.

even i tried to place the tp link router between my main gpon router and openwrt router.. tp link router configure with 1.1.1.1 and openwrt router using the dns server advertised by peers

but still when i connect to openwrt it connect to Marseille france.

also the picture is attached.

Please connect to your OpenWrt device using ssh and copy the output of the following commands and post it here using the "Preformatted text </> " button:

Remember to redact passwords, MAC addresses and any public IP addresses you may have:
ubus call system board
cat /etc/config/network
cat /etc/config/wireless
cat /etc/config/dhcp
cat /etc/config/firewall

Also, please include the ip addresses of all devices upstream of the OpenWrt device.

OpenWrt does not operate cloudflare DNS.

I don't see 1.1.1.1 configured

The OpenWrt can't control the location of your closest CloudFlare data center

Aisfkhan · February 2, 2025, 2:50pm

bro what im saying is i configured my tp link router with cloudflare and then connected my openwrt router through rj45 cable to my tp link router.

now i have 2 ssid one from tp link router and one from openwrt router.

if i connect my devices to tplink router ssid all dns queries goes through my city cloudflare server.
and if i connect devices to my openwrt router ssid which is connected to tplink router through rj45 sent all queries to marsielle france.

openert router should also sent dns quries to my city clouflare data center because it is like an access point now.

lleachii · February 2, 2025, 2:53pm

OK...

Can you show a screenshot of what you mean?

Why do you believe this isn't occurring can you show us?

Is there some configuration you wish to add to the OpenWrt?

Aisfkhan · February 2, 2025, 3:01pm

My phone is connected to to TP-Link SSID

Here my phone is connected to openwrt router SSID.

But TP-Link router is the main router with 1.1.1.1 configured and openwrt router is connected to tp link router as a sub router without configured any dns.

I really do noticed better latency when connected to my city dns server.

brada4 · February 2, 2025, 3:30pm

You can not control anycast routing from your router alone.

LilRedDog · February 2, 2025, 5:25pm

If you had set it dumb it would, but you have it active. You have firewall rules, different subnet ( I asked you for upstream ip addresses).
Set it up as a dumb AP and get back to us.

Aisfkhan · February 3, 2025, 7:17am

bro i tried Dump AP also but again same thing was happening my tplink router connection to my city dns server and openwrt router connecting same Marseille france server.

( I asked you for upstream ip addresses). really don't have an idea what is this.

now i gave up on this i will use google dns as it is connecting to nearest dns server to my city.

moeller0 · February 3, 2025, 7:25am

Please try tho folloqing from the OpenWrt device:

opkg update ; okg install mtr-json # I think that is the corect package name..
mtr -ezb4w -c 100 1.1.1.1 # this takes almost 2 minutes

Then post the output (consider reacting sensitive IP addresses, but please only the last 2 sections). In addition please tell us your city or general region...

moeller0 · February 3, 2025, 7:27am

In dumb AP mode OpenWrt will not perform DNS resolution or configuration of client DNS servers, so unclear how this happened (I am not doubting your report, but note that should not have been possible).

Aisfkhan · February 3, 2025, 7:36am

okay will do this later after i get back home.

jeddah, Sa is my region

moeller0 · February 3, 2025, 7:45am

Mmmh, it looks like a lot of submarine cables land in Jeddah, so if it truly is Marseille (where a bunch of the same cables land as well) that might not be totally terrible, but also not perfect...

Aisfkhan · February 3, 2025, 7:48am

yes and i also configured one.one.one.one in my android phone and when on mobile data it gave me Jeddah, Sa result in dnsleaktest.

Edited

Check

LilRedDog · February 3, 2025, 1:05pm

Let me show you why the DNS server address means nothing:
I have a computer that handles all DNS requests and, depending on how it is configured, I can tell it if it gets confused to use Cloudflare directly.

While I live in the US, I do not live in Columbus and those are not the addresses I put in.

Are you 'encouraged' to use local DNS servers?

Aisfkhan · February 5, 2025, 12:57pm

no i wont use local dns servers.

i tested bufferbloat speedtest 1.1.1.1 still better than all so i will continue using 1.1.1.1

lleachii · February 5, 2025, 1:03pm

Manually enter SA DNS 172.70.156.80 instead of anycast 1.1.1.1.

moeller0 · February 5, 2025, 1:10pm

Still interested to see that...
