Hello,
I would like to make filter that allows communication only between
specified VMs. Those VMs should be specified by their MAC address. The
filter should extend clean-traffic but I was not able to get it working
with that reference. I have came up with modified clean-traffic which works
fine [1]. Is there a way to achieve the same behavior with reference to
clean-traffic?
Thank you.
Best wishes,
Ales Musil
