We have the Swisscom Box 3 with IPv6 enabled (it should remain active). I have now set up a home server installation with its own DNS and wanted to distribute this DNS via DHCP. However, I noticed that despite correctly entering the IPv4 and IPv6 DNS entries, there is another DNS entry (with higher priority) that points to the router. This means that this DNS is used by the end devices.
Since I am not really familiar with IPv6, I looked it up and found that the router sends SLAAC RAs (router advertisements), which include a DNS server in addition to the IP. Is there a way to customize this RDNSS packet and delete the DNS or add my server?
