Configure Multiple Networks in Proxmox

Running multiple networks on a Proxmox cluster might seem like overkill, but separating your traffic is the key to preventing node dropouts, handling heavy Ceph replication, and keeping your homelab stable. In this video, I break down the hardware, explain why I use three separate networks (Corosync, Ceph cluster traffic, and general traffic), and walk you through the step-by-step configuration to set this up on your own Proxmox servers. 🔔 *Subscribe* for more hands‑on cloud tutorials!
