-iPerf requires you to know of a reliable public server with which you can use it. Currently, the official IPerf webpage hosts a short list of public iPerf servers: [[https://iperf.fr/iperf-servers.php|https://iperf.fr/iperf-servers.php]].

-Some iPerf server don't work, so if you receive an error when testing, try a different server. You can also try unofficial iPerf servers, but their location and availability may often change. Once you've configured the Server address, protocol and port, you can start your tests. You'll probably only use Server mode if you're testing an intranet VPN site.

-===== iPerf Notes =====
+===== iPerf Notes and Troubleshooting =====
-Unfortunately, there are currently few reachable iPerf servers. In order to get accurate results, it's important to use an iPerf server with geographical proximity. The above example was run on a 200Mb/s downstream / 12Mb/s upstream connection. However the results are far from accurate. Regardless, IPerf can still be a useful tool for tasks such as intranet VPN performance testing and tuning.
