My testing is with locally-originated UDP traffic (iperf3 -u). Haven't tested what happens if the box is forwarding the traffic - however, I believe TCP socket inpcb route caching should not be relevant for the UDP traffic? (But there is also a TCP transaction between the iperf3 sender and the iperf3 receiver at the *start* of the iperf3 session.) In any case, I will also test what happens if the box is forwarding the traffic.
