Hello Proxmox community,

I'm facing an issue where I'm trying to route all network traffic to one specific virtual machine (VM) in my Proxmox setup, but it's not working as expected. Here's a summary of my configuration:

  • I have a Proxmox host running multiple VMs.
  • I want to direct all network traffic to a particular VM for monitoring or analysis purposes.

much appreciated if someone helps a brother out
You have not provided enough info. What does your network look like? What is your firewall, what kind of switch are you connected to?
I am using pfsense and this is what my interfaces looks like
auto lo
iface lo inet loopback

iface enp6s0 inet manual

auto vmbr0
iface vmbr0 inet static
bridge-ports enp6s0
bridge-stp off
bridge-fd 0

auto lo
iface lo inet loopback

auto eno1
iface eno1 inet manual

auto vmbr1
iface vmbr1 inet static
bridge_ports eno1
bridge_stp off
bridge_fd 0

auto vmbr2
iface vmbr2 inet manual
bridge-ports none
bridge-stp off
bridge-fd 0
