How did you do this?
Did you use the HTTP Sampler "Source Address" field?
And what did you use to populate it?

You might find that the JMeter client and/or network connections to
the JMeter servers are a limitation.

I would suggest running stand-alone JMeter non-GUI instances and
combining the results afterwards.
You can start the test on a single client, and add more clients until
the server under test starts to complain.

In either case, make sure your JMeter hosts clocks are synchronised.

That depends on how you are doing it currently.

Yes, but more info is needed
