Hello all,

Need some advise on my setup. I am not sure if I have setup it correctly. I am unsure if this pihole, ubiquiti or ME issue. :D

I was trying to use one NIC to host multiple VLANS and register devices into pihole. This works for IoT devices but not Trusted Devices.
I checked from my window device and can do nslookup and it shows the pihole address and I can ping the piehole.

Code:
C:\Users\admin>nslookup google.com
Server:  UnKnown
Address:  10.10.53.5

I have Proxmox plugged into Switch port 14 and its set setup on VLAN my server VLAN 60 and from the PVE network tab, I have enabled "VLAN aware" for
Code:
vmbr0

I installed pihole as a container and set the static IP of 10.10.53.5.

1773422583784.pngI have changed all the Network DNS zone to the pihole address.
Why does it only registers the IoT Vlan?

I am at the point of confusion.
 
Hi,

it looks like single NIC’s bridge or switch port isn’t passing those VLANs correctly.
You could try to configure the NIC and bridge to be VLAN-aware, make the switch port a trunk carrying all VLANs, and assign the right VLANs to each VM or container.
