Hi Priyanka,
There must be a packet drop from the client side while returning an ACK
to the server. Again, please check the server has those ports "unblocked"

If I run iperf server on my desktop and run the client on a VM (with
floating IP) on openstack it connects properly.

Then this doesn't look like a Neutron problem. You need to figure out why the
iperf server did not respond. If yo

I would suggest running tcpdump on the server side and see if the packet is
making it to the stack then. Perhaps there are other UFW rules dropping things?
You can just use something like 'telnet 192.168.1.42 5001' to verify that.

Like Krishna asked, have you added a security group rule for TCP port 5001?
Otherwise ingress traffic on that port will be dropped.

Hi,
Sorry my mistake . I was actually trying it for different ports and
copied the earlier command on client VM. On client VM I am running
iperf -c 192.168.1.42

iperf -s
yes the server is listening on port 5001.

Hi,
Have you defined the port in the security groups associated with the VMs?
