Configuring MikroTik to Use Lumiun DNS via DNS53

This configuration will make the MikroTik router forward DNS requests using the traditional DNS protocol on port 53, also known as DNS53 or Do53. Additionally, this setup will ensure that the IP address linked to the Location is automatically updated in Lumiun DNS using MikroTik's native Dynamic DNS functionality.

All devices on the local network using this router as their DNS server will follow the rules defined in the Policy assigned to the configured Site.

When using the DNS53 protocol, the Site link in Lumiun DNS is made with the public IPv4 address of the internet connection where the router is located. Therefore, if there is more than one router using the same public IP address, their rules and reports will be unified in the same Site within Lumiun DNS.

MikroTik Router Configuration to Use Lumiun DNS with DNS53

Access the web management interface of your MikroTik router, for example 'http://192.168.88.1', and log in. After that, click the WebFig button at the top of the page.

Go to the IP → Cloud menu.
Enable the DDNS Enabled option.
Leave the Use Local Address option disabled if it exists.
Click Apply.
Copy the hostname (ending in .mynetname.net) in the DNS Name field and enter the hostname in the Site configuration in the LumiunDNS dashboard to establish the Site link with this hostname.

Go to the IP → DNS menu.
Fill in the Servers field with the two IP addresses assigned to your Site - see what they are on the Sites page. 76.223.1.120, 13.248.132.249, 2600:9000:a418:ffdb:d5fc:e6dc:e22a:ceaf and 2600:9000:a51c:7f39:2f9c:3051:ed89:84f0.
Leave the Use DoH Server field empty.
Ensure the Allow Remote Requests option is enabled.
Click Apply.

Important: make sure your router receives DNS queries only from your local network. If the router is exposed to the internet, configure firewall rules to allow access to port 53 (tcp and udp) only from the local network.

Still in the IP → DNS menu, click on Cache and then Flush Cache.

Go to the IP → DHCP Server menu.
Click on the Networks tab. Click on your listed network, for example, 192.168.88.0/24.
Fill in the DNS Servers option with the same address contained in the Gateway option above. Click OK.

Done! Now you can view the reports in your Lumiun DNS dashboard and also define the Policy rules.
