Hi everyone,


I'm currently setting up a pfSense VM on Proxmox and would appreciate your guidance on properly configuring it so that VMs on the LAN interface (vmbr2) can access the internet, proxmox is installed on ovh dedicated server.


Network Setup

  • Proxmox Host
    • vmbr0: Public IP public-ip/24
    • vmbr1: 10.10.0.1/24 – used for pfSense WAN
    • vmbr2: 10.20.0.1/24 – used for pfSense LAN and other internal VMs
  • pfSense VM
    • WAN: 10.10.0.252 (connected to vmbr1)
    • LAN: 10.20.0.252 (connected to vmbr2)
  • Other VMs
    • Example: 10.20.0.100 (connected to vmbr2)
    • Gateway: 10.20.0.252
