 Surely you've heard of the topic that is currently haunting [[https://www.golem.de/news/wegen-cloudflare-openbsd-deaktiviert-doh-im-firefox-browser-1909-143884.html|IT-News]]. Mozilla will integrate in Firefox [[https://cloudflare.com/|Cloudflare]] as DoH-Server and activate it by default. In itself, it's not a bad idea to encrypt DNS queries so that they can't be read in open networks (like Freifunk). However, it is a thorn in the side of many users and us to use a provider from America by default.
-That's why we have set up a DoH/DoT server for you, which you can for example directly add to Firefox, use via App or combine with another DNS server.

 ===== Addresses & Protocols =====
 Our DNS servers are available both as "normal" [[knb:dns|DNS servers]] (for simple, unencrypted DNS over UDP/TCP), as well as via the following protocols:
-  * DNS over TLS
+  * DNS over TLS ''%%tls://dot.ffmuc.net%%''
-  * DNS over HTTPS
+  * DNS over HTTPS ''%%https://doh.ffmuc.net/dns-query%%''
-  * DNS over HTTP/3
+  * DNS over HTTP/3 ''%%h3://doh.ffmuc.net/dns-query%%''
-  * DNS over QUIC
+  * DNS over QUIC ''%%quic://doq.ffmuc.net%%''
 For configuration, please use the following addresses & domains:
   * ''doh.ffmuc.net - IPv4: 5.1.66.255 / 185.150.99.255  IPv6: 2001:678:e68:f000:: / 2001:678:ed0:f000::''

+===== AVM Fritz!Box =====
+Since Fritz!OS 7.20, it has been possible to configure DoT servers directly in the Fritz!Box.
+Go to Internet -> Account Information -> DNS-Server. At the bottom field, enter dot.ffmuc.net as the hostname:
+{{ :knb:fritzbox_dot_settings_en.png?direct&800 |DoT-Settings in FritzBox}}
+In the Online Monitor, you can now see that the following entries also appear under "DNS servers used":
+:678:e68:f000:: (DoT-encrypted)
+:678:ed0:f000:: (DoT-encrypted)
+.1.66.255 (DoT-encrypted)
+.150.99.255 (DoT-encrypted)
+For one of the four, it also says "currently used for standard queries – DoT-encrypted".
+If that is the case, everything is set up correctly.
+===== Mikrotik / RouterOS =====
+The main problem here is that the devices do not trust the FFMuc Let’s Encrypt certificate by default.
+Therefore, we first need to configure the regular DNS, download and install the certificate, and only then can we configure DoH:
+<code>
+/ip dns set servers=5.1.66.255,185.150.99.255
+/tool fetch url=https://letsencrypt.org/certs/isrgrootx1.pem
+/certificate import file-name=isrgrootx1.pem passphrase=""
+/ip dns set servers=5.1.66.255,185.150.99.255 use-doh-server=https://doh.ffmuc.net/dns-query verify-doh-cert=yes
+</code>
+(The command line instructions are given here. In the GUI, the hierarchy is identical, meaning instead of "/ip dns set" you select the menu item "ip", then the submenu "dns", and set the corresponding values there.)
