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!

    It should work just fine. the proxmox just sets up a bridge to the virtual interface when you install it and after that, VMs you deploy will appear in to everything else on the network as if connected through a switch.

    However, watch out about it your routing tables. If the pihole isn’t on the same network (regardless of if it is virtualized or not), you have to tell other computers on the network how to reach that other network, by making changes to their routing table, or the one in your router (that is literally its job, after all).
