Expected Behaviour:
Pi-hole to act as DNS server.
.
Actual Behaviour:
Pi-hole was running correctly in VM on internal network with Juniper Router / Firewall. Switched to IPFire Router / Firewall (which requires DNSSEC for DNS) and cannot now use pi-hole as IPFire will not accept pi-hole ip as DNS server. I've ticked DNSSEC in pihole settings and change DNS server to Quad 9 but IPFire will still not accept pi-hole as DNS server.
Debug Token:
Any help appreciated!
