The problem here is that iperf transmits no data (0 bytes), which is not greater than 0.
Test output (stderr) shows that iperf3 fails with an error:
iperf3: error - control socket has closed unexpectedly
command terminated with exit code 1
iperf pod is in hostnetworking mode, if that makes a difference.
Host endpoint has no policy enforcement, but has not seen any traffic either:
/sys/fs/bpf/tc/globals/cilium_policy_01097:
POLICY DIRECTION IDENTITY PORT/PROTO PROXY PORT BYTES PACKETS
Allow Ingress 0 ANY NONE 0 0
Allow Egress 0 ANY NONE 0 0

iperf3-server-9pf5x, the source pod is on k8s2, with IP address 192.168.36.12. It's trying to reach 192.168.36.11 so we don't have any visibility on that traffic (BPF programs are attached on native devices but monitor aggregation is enabled so no {to,from}-network traces).
According to test-output.log, the iperf3 client failed with:
iperf3: error - control socket has closed unexpectedly
The server failed with:
iperf3: error - unable to read from stream socket: Bad file descriptor
Many reports of this error on the iperf repository, so probably fairly generic.
We are missing the SCTP ss output to be able to check the listening/established connections. I'll send a PR to fix that. We can also temporarily disable monitor aggregation for that test.
