It does. Note it doesn't listen to IPv6 by default so if you're using
that you need the -6 option.
IIRC iperf3 checks the system clock very frequently making it a bit more
of a benchmark of clock reading than network bandwidth on machines where
reading the clock is slow. IIRC iperf 2 is better for that, or there's
tcpbench in the base OS.

Sending what should be local traffic to the ISP suggests that something
is wrong with either the routing table or firewall rules on the router.
