Connect Opnsense -> vSwitch -> Opnsense

[QuratorJohn]

Hi all, the task is to connect two Proxmox hypervisors to a VM: OPNsense to Hetzner using vSwitch.

The interface on both servers has been configured:
# /etc/network/interfaces auto vmbr0.4000 iface vmbr0.4000 inet static address 192.168.100.1 (192.168.100.2 on the second server)
netmask 255.255.255.255.0 vlan-raw-device vmbr0 mtu 1400

And that's how proxmox servers can ping each other.

But I don't have enough knowledge how to route these VLANs in OPNsense so that they can communicate with each other. The vmbr0.4000 interface cannot be assigned to a virtual machine.

Please, if you have any idea, tell me how to present this vlan in opnsense
