Hello, Thanks for commnent. I then wonder how you can get lost in my short communication, in contrast to ton of material you ever read to get a pro.
I truly don't think why minimal VETH/MACVLAN config shall reflect the inbound traffic for anybody to see (in ESXI environment at least) -- where is it documented please? Thanks for teaching me here.

Reflecting packets via the network infrastructure is normal behaviour, if configured this way.
