Hello, I tried to measure network performance BTW VM which connected through GRE tunnel. So, I configured neutron(ML2/GRE).
Then I verified TCP performance between VMs which are placed on same host.
But I could not make Iperf connection BTW VMs (on other host), but ping is ok.
bellow things are current Security group configuration. I think that I allow all traffic which is needed to execute iperf.
