iperf-2.0.14a-Nov30 (both windows and linux, TCP and UDP tests) -r and -d doesn't work
communication between tested machines is ok:

Can you try with --full-duplex too?

Thanks,
Bob

[Przemo]

--full-duplex works ok

[Robert McMahon]

I haven't been able to reproduct this so far. Does --reverse also work? Do older versions, e..g. iperf 2.0.13, work? It shows like a firewall problem but could be something else.

[Robert McMahon]

Ok, I reproduced it. I'll debug tomorrow PST

[Robert McMahon]

Ok, should be fixed. this was a regression. Thanks for finding it
