Hello everyone,

I hope you’re all doing well. I’m reaching out for some guidance on a network project I’ve been working on.

Currently, my setup includes:

  • OPNsense Firewall: This is running smoothly and is the primary gateway for my network.
  • Proxmox Server: I’m in the process of integrating this. It has a single Ethernet port for network connectivity.

My primary goal is to deploy a Pi-hole instance on the Proxmox server. I’m still weighing whether to go with a Docker container or a standalone VM for this.

Here’s the crux: My existing network devices operate in the 192.168.0.1xx IP range. I’d like the Pi-hole to be on a different subnet, specifically 192.168.33.xxx. This move is mainly for organization and segmentation purposes.

Considering the single Ethernet port on the Proxmox server and my intended setup, is this feasible? Moreover, are there specific challenges or configurations I should be aware of?

Any insights, advice, or shared experiences would be invaluable.

Thank you for your collective wisdom and time!

    Subnetting and VLANs can get hard to conceptualize when they are virtualized on a single machine.

    I’d suggest going to draw.io and making a logical network diagram so that you can have a reference when setting up your network.

    If you want EVERYTHING going through piHole which is on a different subnet, easiest way I’ve done it was make going through the pihole necessary to make it to the default gateway.

    But if you have a different situation for pihole you can set up DNS relays.

      yeah I should draw it out first. Right now traffic is routed trough a pihole on a raspberry

      I think I will keep this route
