The issue I am facing:
I followed this guide to a T. Pi-hole and OPNsense – Pi-hole
Pi hole started registering queries but my devices could not access the internet. I would get a DNS probe error on attempting access.
The issue seems to be this section:
"This next step configures OPNsense to send it’s own IP address as the DNS server for client DHCP leases. This uses the dnsmasq that we configured in the previous step. The example OPNsense router’s IP address is 192.168.88.2. Set this value in “DNS Servers”."
So in my world, I tried setting to 192.168.1.1 but it doesn't like this. If I change this to 192.168.1.3 the internet opens up again. I know this is not the intended setup but I can't figure out where I am going wrong.
Details about my system:
Opnsense on zimaboard at 192.168.1.1, pi hole on unRAID at 192.168.1.3
What I have changed since installing Pi-hole: nothing but what is in guide above
Ip in below is pi hole (.3)
