I have a problem trying to setup a pi-hole dns server correctly.
I have the pi-hole server residing in the green zone (10.1.1.99).
The pi-hole is setup to use IPFire as external DNS server (10.1.1.1).
IN the Domain Name System of IPFire I have a valid external network.
In the Advanced Web Proxy Configuration of IPFire I have Advanced Web Proxy enabled and transparent on green with the default ports (proxy: 800 & transparent: 3128) and no Upstream Proxy configuration.
In the DNS Forward Configuration I have one entry Green (DNSSEC disabled) pointing to the ip of pihole (10.1.1.99) and enabled.
I am expecting all clients in the Green zone to automatically use pi-hole as DNS server, unfortunately my browsers requests do not seem to use pihole but go straight to the IPFire DNS server.
I am also aware that internally, between my clients and pihole, DNSSEC will not be operational.
The pihole log show no activities and the blocks do not work.
What am I missing here?
