Can anyone tell me if theirs a way to forward HOST name information from my Opnsense routers DHCP services on to my PiHole. I can only ever get CLIENT IP address information when viewing PiHoles query log. I have to keep looking up what IP belongs to what device via Opnsense DHCP list each time I'm investigating alerts and stuff on PiHole.
It would be nice if I could as I don't really want to keep logging in to one device and then having to log in to the another for confirmation.
Services: Unbound DNS: General
DHCP Registration->check
Your PiHole then needs to use the OPNsense as nameserver for the reverse lookups.
Yes, just turn on DHCP Registration as stated above (also DHCP Static Mappings if you use them). In Pi-Hole, turn on Conditional Forwarding under Settings --> DNS and set it up per your network configuration.
You can also add the line "NAMES_FROM_NETDB=true" (without quotes) to the /etc/pihole/pihole-FTL.conf file. See here for an explanation of this setting: https://docs.pi-hole.net/ftldns/configfile/ (https://docs.pi-hole.net/ftldns/configfile/)
