with the demise of ESXi, I am looking for alternatives. Currently I have PfSense virtualized on four physical NICs, a bunch of virtual ones, and it works great. Does Proxmox do this with anything like the ease of ESXi? Any other ideas?

    I have another question, if you don’t mind: I have a debian/incus+opnsense setup now, created bridges for my NICs with systemd-networkd and attached the bridges to the VM like you described. I have the host configured with DHCP on the LAN bridge and ideally (correct me if I’m wrong, please), I’d like the host to not touch the WAN bridge at all (other than creating it and hooking it up to the NIC).

    Here’s the problem: if I don’t configure the bridge on the host with either dhcp or a static IP, the opnsense VM also doesn’t receive an IP on that interface. I have a br0.netdev to set up the bridge, a br0.network to connect the bridge to the NIC, and a wan.network to assign a static IP on br0, otherwise nothing works. (While I’m working on this, I have the WAN port connected to my old LAN, if it makes a difference.)

    My question is: Is my expectation wrong or my setup? Am I mistaken that the host shouldn’t be configured on the WAN interface? Can I solve this by passing the pci device to the VM, and what’s the best practice here?

    Thank you for taking a look! 😊

        My config was more or less identical to yours, and that removed some doubt and let me focus on the right part: Without a network config on br0, the host isn’t bringing it up on boot. I thought it had something to do with the interface having an IP, but turns out the following works as well:

        user@edge:/etc/systemd/network$ cat wan0.network
[Match]
Name=br0

[Network]
DHCP=no
LinkLocalAddressing=ipv4

[Link]
RequiredForOnline=no

        Thank you once again!
