Local DNSSEC cannot be used via the FRITZ!Box

DNS requests 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).

Cause

  • Error in FRITZ!OS 7.50

1 Installing the latest FRITZ!OS

To use the DNSSEC validation with devices connected to the FRITZ!Box, the latest FRITZ!OS must be installed on the FRITZ!Box.

  1. Install the latest FRITZ!OS on the FRITZ!Box.
