Local DNSSEC cannot be used via the FRITZ!Box

DNS queries are not resolved via the FRITZ!Box if the devices use a DNSSEC validation (i.e. an authenticity validation of DNS entries for a domain).

The problem affects both their own local DNS servers in the home network (for example Pi-hole, Bind9), which are announced via the FRITZ!Box DHCP server, and connector in doctors' offices and pharmacies (for example Gematik, secunet).
