Jperf can start up a client or server. It can not start up a client or
server on a remote machine. So if you wanted to measure between C and A,
you would need to have a server on A and a client on C, which can be
started up using just Iperf or using the gui Jperf. This is assuming that
A&C can talk directly to each other, but it doesn't sound like you have it
set up so B forwards traffic to C or anything. If A can't talk to C, then
if you wanted the complete path you would need to have a client on C,
server on B do measurements, then a client on B and a server on A, then do
measurements. Or something like that.

Note. You must have iperf installed on any machine you want to start a
client or server on using Jperf.
