DHCP in dual subnet setup

[deHakkelaar]

@dronec

Is there any way to add an extra config file for this scenario?

I havent tried it myself and there was no reply on below suggestion that I think could work:

DHCP for second interface

Pi-hole configures DHCP like so: pi@ph5b:~ $ cat /etc/dnsmasq.d/02-pihole-dhcp.conf ############################################################################### # DHCP SERVER CONFIG FILE AUTOMATICALLY POPULATED BY PI-HOLE WEB INTERFACE. # # ANY CHANGES MADE TO THIS FILE WILL BE LOST ON CHANGE # ############################################################################### dhcp-authoritative dhcp-range=10.0.0.11,10.0.0.254,24h dhcp-option=option:router,10.0.0.1 dhcp-…

Tail the logs live to see whats happening when you connect a device to either segments:

sudo tail -F /var/log/pihole/pihole.log | grep dnsmasq-dhcp

EDIT: Oh I noticed you'd might want to advertise a different router IP for the second subnet.
Then it should be below if eth1 were the second interface name ... as an example:

$ sudo nano /etc/dnsmasq.d/99-my-dhcp.conf
# Subnet network2.dehakkelaar.nl
domain=network2.dehakkelaar.nl,192.168.2.0/24,local
dhcp-range=eth1,192.168.2.50,192.168.2.250,24h
dhcp-option=eth1,option:router,192.168.2.1
