Cannot access Network Mgmt Interface - PFsense Setup

[Jedi2155]

Hello! I've installed ProxMox with a Pfsense install where I have 4 network interfaces that are all natively passthrough (added as a PCI Device) to improve performance. I'd like to the make the gateway accessible on any of the LAN interfaces without using a Linux Bridge if possible. It was previously possible to communicate with both the VM / ProxMox when I was using a bridge, but now that I'm natively passing the NIC, I can't seem to talk to Proxmox.

This is the current output of nano etc/network/interfaces but I have to use a USB network adapter to connect to PVE​

auto lo
iface lo inet loopback
iface enp89s0 inet manual
#LAN3
iface enp87s0 inet manual
#LAN2
iface enp2s0f0np0 inet manual
#pfSense WAN
iface enp2s0f1np1 inet manual
# pfSense LAN
iface wlp90s0 inet manual

auto enx9cebe89342cb
iface enx9cebe89342cb inet static
        address 192.168.1.5/24
        gateway 192.168.1.1
#Dell USB NIC Mgmt

Interface used with Linux bridge. This worked as long as I used the linuxbridge with PFsense.​

vmbr0
iface vmbr0 inet static
    bridge-ports enp2s0f0np0
    bridge-stp off
    bridge-fd 0
#pfSense WAN

vmbr1
iface vmbr1 inet static
    address 192.168.1.5/24
    gateway 192.168.1.1
    bridge-ports enp2s0f1np1 enp87s0 enp89s0
    bridge-stp off
    bridge-fd 0
#pfSense LAN

When I removed vmbr0, and re-assigned the WAN/LAN interfaces directly as above, I lost the ability to communicate to the management interface and I'm lost as to a solution.

I understand u have a 4 port network card. Its passthrough to the vm. Then these is no net port or bridge where u can define an host IP. You need one of them.

Thank you for the detail. It sounds like the best solution at this point is assign one of the ports into a virtual linux bridge, assign the host/gateway there, assign that port to the VM, and then reconfigure pfSense accordingly.

Well, I finally got it to work after an 2 hours of tinkering since ProxMox / PFsense port mapping is a little confusing as well as the bridge configuration. I just reconfigured one of the native ports into a linux bridge port. I then setup a pfSense bridge between the interfaces I wanted to give PVE access to. The odd thing was that PVE would not allow access to the web config tool without putting in the linux bridge.
