1.) It uses either TCP or UDP (you get to choose) so as long as the
network can route standard IP traffic, it will work.
On the server, do `iperf -s`. On the client, do `iperf -c
WWW.XXX.YYY.ZZZ` (where WWW.XXX.YYY.ZZZ is the server's IP). `iperf
--help` gives you all the options.
2.) Depends on how the traffic is routed. If you have two devices on the
same network, but the traffic for them is routed out to the world and
then back (because of how their subnets are configured, for example),
then the traffic will go out to the world and then come back. So, it
comes down to "it depends", and you'll need to see what your network
topology is like (for example, with something like traceroute) and the
speed you'll get is the actual speed. You'll have to determine where the
bottleneck is based on how your network is set up. For example, if you
are just 1 hop away, then it's almost certainly limited by just the
media. But, if you've got several hops, then you may be limited by the
router that is passing traffic between the networks, or the links that
connect different switches or routers, or whatnot.

This is Abdullah Alabbas a networking engineer that works in a
school. I read about the iperf tool and fall in love with it and
like to know how to test the bandwidth of a wan connection where
the server and client would be in two separate network. It worked
with me when I was testing through a local network (I mean where
two devices are in one network).
My questions:
1) how to test the bandwidth of a wan link where two devices in
two separate network?
I searched online to see a simple set up to test the connection
between two devices in two separate network, but does not see a
result...
2) if I am testing two devices in the same network, would they
test the media between them only? Or, they actually testing the
wan link that connect them to the network? in another words, are
the numbers purely for the wan connection or they are affected by
the media that connects them (wired or wireless)?
Please I appreciate your help if ASAP...
Thanks,
