Unicast vs. multicast seems to make no difference.
What makes a difference however ist disabling multiqueue in proxmox. Removing the queues=X parameter completely mitigates the issue.
However, I know of two other OPNsense on Proxmox installations that do not have this issue and run fine with queues=8.
Mystery.
