Pihole, VLANs & VPN

[bombz88]

Hello,
I currently have my PiHole setup for years across all my 'corp' VLANs 10.200..
I have (1x) VLAN outside this range 10.12.12.*
This network is a WiFi guest network.

My gateway handles all DHCP of the network.
I also have a firewall rule that allows all network ranges to the PiHole IP.
When connecting to a VPN from the 10.12.12.* network, is there a way to push that traffic through the pihole?

Thank you.

You would need to do this in the VLAN management software. Route port 53 traffic across VLANs.

I also route traffic from different VLANs to pihole.
But you could also add virtual interface to your device hosting pihole for every VLAN

That's because you are doing it wrong! Don't route DNS Traffic from VLAN to VLAN but instead add some VLAN Interfaces to your Pi-Hole Server so it has a simple local connection with every Client in each VLAN If you want I can write up a Tutorial for this in English ?

to clarify, All the VLANs are hitting the PiHole and working accordingly.
I am not sure if I am able to route the VPN traffic through the PiHole. As when I connect to the company VPN, nothing is routed through the PiHole, which makes sense (kind of). Trying to figure if I can resolve this concern now.
Thanks for the followups!
