Configure DNS Forwarder to internal DNS server?

[W_Colony]

First attempt at pfSense...
I'm using Pihole as the DNS server on my network. I want to setup the pfSense DNS Forwarder to use the Pihole as the primary DNS and then have an internet server as the secondary. From what I can see in the documentation it appears that it just blindly uses the WAN link's DNS.

So how can using the internal DNS server as primary be accomplished?

@w_colony Normally you would point your clients to pihole, and then have pihole forward to pfsense. Pfsense can then either forward or resolve.

If you have some local domain that pihole is going to resolve local resources that you want pfsense to be able to resolve, then setup a domain override for that domain to point to pihole.

If you point your clients to pfsense, and then have it forward to pihole - you won't have any info in pihole on which client requested what - which is one of the nice things about pihole. You know what client is asking for whatever..

I currently use such a setup, clients point to pihole. Pihole forwards to pfsense (unbound in resolver mode)..
