Comment 5 for bug 1883321

Hi,

one more observation from my test system.

If I want to ping from VMa to VMf which are in different L2, but on the same compute node. The traffic reaches the VMf but the return traffic is not correct forwarded.

I also updated my test system to Centos 8.2 but nothing changed.

I've made a list of all the cases I've tested.
All test were done with agent_mode=dvr_no_external and only VMa has a flowting IP.

Best Regards
Phil
