Hello,

I have a pfsense firewall with a unifi layer 3 switch. I just enabled 4 vlans 0,1,2,10. All 4 vlan are configured on the same NIC. The switch have vlan 0 as third party gateway and vlan 1,2 and 10 are configured to be routed in the layer 3 switch. All DHCP are on pfsense.

Unifi create a vlan4040 for inter-vlan networking and it’s configured also in the pfsense firewall without DHCP.

My pihole is on vlan 0. In the network tab, I have the hardware ID of everything on vlan 0 but none on vlan 1,2 and 10. Pihole is configured for conditionnal forwarding 192.168.0.0/16 to pfsense

For now, the only way I fixed that is to put a pihole on each of the vlan and configured each dhcp to talk to these pihole but there’s surely a better way to do that? My goal would be to have only 2 piholes (HA) for all vlan.

Thank you
