Fritzbox - IPFire - (green)Switch - Raspberry as DNS (with Pi-hole and unbound)
If i use the green IP of IPFire as Gateway and the IP of the Raspberry as DNS all works fine.
My question is how to configer the IPFire (Domain Name System) to use the IP of IPFire as DNS?
With no entry in the Domain Name System section of IPFire, i have Status: Working (Recursor Mode), i guess IPFire use my fritzbox as DNS
if i enter the IP of my Raspberry i get rDNS Reverse lookup failed
Use ISP-assigned DNS servers is disabled.
thanks in advance
p.s. German answer is also ok
