Custom Forwarding on Pi-Hole
How to configure custom forwarding on Pi-Hole
By default, as of FTL 5.8.1, Pi-Hole has limited support for Conditional Forwarding in the web UI. This limitation of only being able to add one conditional forward can restrict more advanced use where specific domains may need to be forwarded to other domain DNS servers, such as VPN to corporate resources.
Custom DNS Configuration
PiHole leverages DNSMasq. Additional configuration can be added to
/etc/dnsmasq.d/ as conf files.
Create a new file such as
sudo touch /etc/dnsmasq.d/02-custom.conf
Add required configuration lines as follows using a text editor of your choice
server=/<domain>/<DNS Server> e.g. server=/mydomain.com/192.168.1.1
