Folks,
I’m looking at running a ntop setup in an Ubuntu server 22.04 VM. One of the Ethernet ports on the Proxmox host is connected to a mirror port on a physical switch. All of the traffic on the mirror port is visible via tcpdump on the Proxmox base system if I watch the physical interface.
However, in the VM with a listener interface connected to the bridge, I only see multicast/broadcast traffic, even if the listener interface is in promiscuous mode. If I run tcpdump on the Proxmox host on the tap interface, I only see multicast/broadcast traffic as well.
Is there a way to set this up so that the tap interface (and thus the VM) sees absolutely everything on the bridge?
Many thanks
