Dear OVS Community! I work the following setup: on my server I run 5 VMs, 3 of which runs an ovs on top of them. Somewhat similar to this: Server-->OVS-->OVS-->OVS-->Server I try to measure the throughput between the two servers with iperf3. I can see with tcmpdump, that the SYN packets go through my network and arrive to the server on the right end, but it does not recognise them, and does not send back a SYN-ACK. I've also tried to switch the roles so that the server on the left becomes the iperf3 server, and the server on the right the iperf3 client, but the same problem appears. When I run the iperf3 client on the most right switch - which is directly connected to the server on the right - the experiment works without any problem. But as soon as there is at least 1 switch in between, I do not get any results.
Can you please help me figure out the problem? Thank you in advance. Kind Regards Zsolt
