Hi,
Let me start off by saying, I'm brand new to ph-hole and seriously ignorant about it.
My issue:
I have a pretty simple home setup with a few vlans. However, Pi-hole only responds to DNS queries on the same vlan. Devices on my WiFi vlan are blocked. Here's the error: "ignoring query from non-local network 10.10.30.50"
My VLANs are such:
Default network vlan 1 - is this for network hardware and does NOT use pi-hole for DNS.
Servers network vlan 10 - all servers including pi-hole are on this vlan and use ph-hole for DNS without issue.
Clients-WiFi vlan 30 - all non-IoT wifi clients like laptops. Can't resolve DNS via pi-hole.
IoT vlan 99 - this vlan is isolated from all other vlans and uses 1.1.1.1 for DNS.
Cameras vlan 60 - settings same as IoT.
Goal:
The only vlans that need to use pi-hole for DNS are vlans 10 & 30
10.10.10.0/24
10.10.30.0/24
looking at the documentation I see this option to "Respond only on interface enp2s0" https://docs.pi-hole.net/ftldns/interfaces/
But I can't find this setting. I've looked through the settings and don't see that option.
Web Interfacev5.21
On my router, intervlan routing between the servers and clients-wifi is allowed. They are both trusted networks.
I thought this would be something simple to fix but clearly I'm dumb. I've read a lot of post about others having the same issue but they were running far more complicated setups or pi-hole on Docker. I'm running pi-hole on an Intel NUC on OS Ubnutu (latest version).
Would anyone know an easy way to fix this?
Thanks in advance and sorry for my ignorance...I'm still learning. lol
Note that VLANs are essentially managed by your router, so you'd need to configure that to route DNS traffic to your Pi-hole machine. It would depend on how your router supports that, and potentially what router port Pi-hole would be connected to whether your Pi-hole machine would be required to feature interfaces for each of the VLANs you want it to serve DNS for (as nero355 has suggested), or whether your router would provide direct inter-VLAN traffic, or perhaps NAT requests to Pi-hole (in which case your router would appear as a client in Pi-hole, aggregating all of a VLANs DNS request)
Likely, yours is already correctly configured to route traffic directly, since you mention:
That would indeed suggest that you'd only have to configure Pi-hole to process those queries instead of ignoring them.
You'll find this under Interface Settings on Pi-hole's Settings | DNS pane, labelled as Respond only on interface eth0 or similar.
If the interface name is missing or not denoting the expected interface, you should consider running pihole -r with Reconfigure and pick the correct one.
I’ve did what @Bucking_Horn indicated on my router, and all DNS traffic from my VLANs is handled by Pi-hole. Basically any DNS request is sent to my Pi-hole.
They updated the setting screen since their guide was written so what I was seeing vs the guide is different. After checking that option inter vlan DNS is working.
