Good day all.
Was wondering if anyone has been able to successfully setup port mirroring within Proxmox using VMs? I have a home lab where I’d like to packet capture on all inbound & outbound traffic from the test workstation and server VLANs.
Usually port mirroring is done in the switch. Not sure I have seen it done on a hypervisor host.
I recall looking at security onion and trying to do this in a vm, I didn’t succeed. However, if my understanding is correct, in Proxmox the default switch is Linux Bridge, though it can also use open vswitch as an alternative, I believe with this you can do port mirroring. I wasn’t able to wrap my head around this but you might want to give it a look.
