dhcp-to-dns

Get list of DHCP static reservations from pfSense and create corresponding DNS records in pi-hole.

Prerequisites

You must install and configure the API for pfSense (see https://github.com/jaredhendrickson13/pfsense-api).

Caveats

I couldn't find a documented pi-hole API for creating local DNS records, so this script relies on logging in via the pi-hole web interface using a cleartext password. I don't like it, but "it is what it is".

Configuration

Copy config.js.example to config.js and set the options below. Read any mention of "pi-hole" as "pi-hole web interface" and "pfsense" as "pfsense web interface".

pihole_address - The DNS or IP address of pi-hole
pihole_protocol - The protocol (HTTP or HTTPS) used to access pi-hole
pihole_port - The TCP port pi-hole is listening on
pihole_password - Cleartext password you use to log in to pi-hole
pfsense_address - The DNS or IP address of pfSense
pfsense_protocol - The procotol (HTTP or HTTPS) used to access pfSense
pfsense_port - The TCP port pfSense is listening on
pfsense_client_id - The client ID for the pfSense API
pfsense_client_token - The client token for the pfSense API
domain - The top-level domain to append to DNS records. For example .lan will create records such as example.lan or myserver.lan
