Hi folks,

It's time for some tinkering with the home server and network. Before I embark on my journey, I would like to hear your thoughts about any pitfalls or dos/don'ts you can see in my plan. Please let me know your comments or tips on the below.

The WAN uplink is provided by my ISP's router (Vodafone, static IPv4/6), and I have a workstation with dual PCIe nic (passed through) and Lenovo miniPC as well as a Synology NAS.

I want to create a 2-node cluster (with a separate QDevice in a Docker container on the Synology) and use OPNSense in a high-availability set-up on the PVE nodes.

The mini PC has one built-in network interface connected to the LAN's switch, and I will use an external USB3 gigabit dongle to connect it to a port on the ISP's router. On the workstation, one PCIe dual port NIC port will go to another port in the ISP's router and the other to the LAN switch.

I'll attach a basic diagram to illustrate my network :)

My key questions are:

What IP addresses should the various pieces have? 10.0.0.0/24 for the ISP router and WAN ports on the PVE nodes. 192.168.2.0/24 for the LAN ports and separate 192.168.1.0/24 for the VMs and anything connected to the LAN switch, served by the OPNSense router. Does this work, or am I overcomplicating things?

I was actually thinking of the same. 2 nodes with qdevice on docker in synology. What docker image are you planning to use?
