Question about iperf -B option

["David Ruiz" <david.ruiz --at-- gigle.biz>]

Hello,

I am trying to do some performance testing with two external powerline
adaptors. For this, I have a single PC with Linux, and two ethernet cards,
each one connected to each of the adaptors. My objective is to send data
generated with iperf through eth1, so that it goes to the adaptor 1 and
via powerline arrives to adaptor 2 and then to eth2.

In order to do this i configure the server as :
iperf -s -u -B 10.10.1.2 (10.10.1.2 is the IP of eth2)

and the client as :
iperf -c 10.10.1.2 -u -B 10.10.1.1 (10.10.1.1 is the IP of eth1)

As far as I can tell, the data arrives to the server, but they use the
loopback. Does anybody know if this can be done (and how??)

Thank you
