I am using iperf between my server and clients. By using -d or -r we are supposed to get downlink and uplink throughput either after each other or every other ones, but after about 1 minute, only throughput for downlink is acheived and we can't see anything more after that for the other way round of the link.
I mean we only get throughput of one side.
I would appreciate if some one can help or give me some hints regarding this problem.
Thanks a lot.
