Comment on Proxmox, OPNsense VM with two ethernet ports issue.

Add each hardware NIC to its own Linux bridge. Add two VNICs to the opnsense VM. In proxmox gui, assign an address to the LAN Linux bridge for the management interface. That’s what I do and I’ve had no problems for over a year. It works fine with near 1gbps symmetrical connection.
