How is iperf3 meant to work?

[Taomyn]

I just installed iperf3 service on my firewall and got the Windows client downloaded to a few PCs. I can start the service and create an instance. I then run the client pointing at the firewall IP and port and get a successful test - great.


However, how am I supposed to perform the client test again? If I try the same test either on the same PC or on another it fails to connect - the firewall doesn't show any signs that anything is wrong. The only way I can start another test is to restart the iperf3 service, create a new instance which then starts but usually on a new port. There's no option from the iperf3 diagnostic page to restart it or do anything else.


Is is expected behaviour or am I missing something?

that is expected behaviour - there is only one test started and after that the iperf tool exits and outputs its data. When you need another test, my script ensures that a port is used which is not in use and not forwarded. This and the firewall rule management is what the background service does except starting iperf3 instances.

Ok, then maybe the GUI should make that a bit clearer and also reset itself so you can submit a new instance more easily - having to change screen to restart the service isn't very friendly.


But at least it works, thanks.

the service is API controlled - if you want to do mass tests, you can create a new instance in a single curl command.
