+## Context
+
+Before diving into the OPNsense configuration, a little bit of context to understand the choices I made.
+
+In my Proxmox VE cluster, I've created 2 VMs and installed OPNsense. The goal is to replace my single physical box by this cluster. Each VMs have 7 NICs for each network:
+- **vmbr0**: *Mgmt*
+- **vlan20**: *WAN*
+- **vlan13**: *User*
+- **vlan37**: *IoT*
+- **vlan44**: *pfSync*
+- **vlan55**: *DMZ*
+- **vlan66**: *Lab*

 Hopefully the next time, I will also cover the VM creation on Proxmox and how I'm preparing this migration from my physical OPNsense box to this highly available cluster in VMs. Let's dive in!
