How to set up bridge with single MAC address to pfSense

I just got a new dedicated server. They do filter MAC addresses, so I was advised to put proxmox into bridge mode. I have 3 public IP addresses all on the same subnet.

I have tried everything but can't get any of the VM guests to be able to access the network. Ideally I want all the systems to go through pfSense, and management would be through a VPN.

Here is my proxmox /etc/network/interfaces config

Code:
auto lo
iface lo inet loopback

auto eno1
iface eno1 inet static
        address  38.xxx.xxx.39
        netmask  255.255.255.0
        gateway  38.xxx.xxx.1
        post-up echo 1 > /proc/sys/net/ipv4/ip_forward
        post-up echo 1 > /proc/sys/net/ipv4/conf/eno1/proxy_arp

auto vmbr0
iface vmbr0 inet static
        address  38.xxx.xxx.52
        netmask  255.255.255.0
        bridge_ports none
        bridge_stp off
        bridge_fd 0
#pfSense WAN

auto vmbr1
iface vmbr1 inet manual
        bridge_ports none
        bridge_stp off
        bridge_fd 0
#pfSense LAN

I believe I know the correct MAC address of the interface. It's listed in the supermicro IPMI as System LAN1 MAC address. I've copied that address to proxmox / 100 / network device (net 0)

Any help would be very much appreciated.
