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.
So far you have talked about namespaces veth and macvlan devices and
vSwitch and nowhere have you actually explained how these are actually connected together and configured.
In the Google doc you linked earlier you showed connections between VMs
and vSwitches, but nothing about the virtual devices on each VM.
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?
I think there's been some confusion here. Bastian (and I) thought you
were talking about the usual VEPA mode of macvlan, where macvlan devices attached to the same underlying device are not bridged and all packets transmitted on a macvlan device are then forwarded to the underlying
devices.
But on re-reading it seems like you are saying that packets received on
the external interface of the VM are being forwarded back out of that
same interface. I would agree this is unexpected behaviour, but until
we see your actual configuration it's impossible to know whether this is
a bug or misconfiguration.
Ben.
