DNS server set up
Hi,
I am trying to set up a DNS server in my wifi router.
I have a PPoE type connection.
I went to the Network section then clicked on Advanced and entered DNS server addresses in 'set DNS server manually section.
Then after restarting the router and my devices , I ran DNS leak test. The results showed me that my desired DNS server addresses was not set in the router. I have made sure that I haven't set any DNS server addresses on my devices or inside the browsers . I use a windows 11 computer and and an Android phone. Kindly help me to solve this problem.

Hi,
Note that big DNS providers (like 1.1.1.1 and 8.8.8.8) will route your requests to servers with other IP addresses.
I suggest you do a Whois lookup for the IP addresses shown by the leak test to see to whom they belong to. In case they belong to the same DNS provider whose DNS server addresses you entered into your router, then I would say everything is good.

Hi,
My internet service provider uses Google.
I changed and tested various DNS service provider's DNS addresses, for example, quad9, cloudflare and adguard.
The result is the same.

Ok.
What about your web browser's settings?
By now, all the major web browsers have a "secure DNS" feature built in. However, if this feature is activated in the web browser, then it will override the DNS settings of the router and there is noting the router could do about it. Therefore, verify that any such feature is switched off in the web browser.

Secure DNS is disabled. I have also attached computer's ethernet settings. It is now set to default automatic.

Is the "IPv4 DNS servers" address shown on your last screenshot identical to the LAN IP address of your TL-WR845N ?

Then I don't know why it doesn't work.
If, for example, the field "DNS Server" for the PPPoE connection has the value 1.1.1.1 and the client devices receive the LAN IP address of the router as their DNS Server's IP address, then the DNS requests of the client devices should be routed to Cloudflare's servers, but not Google's.
As a last resort you could try to update your TL-WR845N to a newer firmware version, but I actually doubt that the current firmware in your router has a bug that defaults the DNS Server to Google's.
