Hi friends. I have a wireguard server on a Brume 2 and a wireguard client on my mobile SlateAX. I’m usnig iperf3 on both to test throughput speeds, and so far so good using basic settings.
However when I try to test UDP with the -u command, the client just sits there, and the server outputs a lot of zeros:
Before adjusting the MTU system wide, you can try to adjust the packet send by iperf3 with --length 128 (very small, but should definitely not fragment).
