I hope you have enjoyed this howto article, you can find many more MikroTik Tutorials here.ĭid this work for you? Let me know in the comments section below. Now you have DNS over HTTPS configured on your MikroTik Router. In my configuration to cloudflare I can see multiple https connection to 1.1.1.1. To verify that DoH is configured and working run torch on your WAN interface and verify you see no udp or tcp connections to DNS port 53.

I used a RB4011 router running RouterOS v6.47beta60 during testing. UPDATE: RouterOS v6.47 was released to the stable channel on June 2nd 2020 with DNS over HTTPS support. A goal of the method is to increase user privacy and security by preventing eavesdropping and manipulation of DNS data by man-in-the-middle attacks by using the HTTPS protocol to encrypt the data between the DoH client and the DoH-based DNS resolver.
It is similar to DoT (DNS over TLS) but not exactly the same.ĭNS Queries over HTTPS (DoH) is an accept IETF standard RFC8484.ĭNS over HTTPS (DoH) is a protocol for performing remote Domain Name System (DNS) resolution via the HTTPS protocol. DoH is a protocol for performing remote DNS over HTTPS protocol. The latest stable version of RouterOS 6.47 adds support for DNS over HTTPS or DoH. In this MikroTik Tutorial I will show you how to configure DNS over HTTPS on your MikroTik router using either Cloudflare DNS servers or Google DNS servers.
