Hello together,
when I do an iperf test with OPNsense running on a Supermicro X11SBA-LN4F as server and an linux box as client, OPNsense sends a TCP reset after receiving some kBytes, see attached pcap.
The linux box and the firewall are connected via an managed HP OfficeConnect 1920S.
Additionally, when I try an iperf test between two linux boxes connected to different interfaces/subnets, I see TCP retransmissions on the client side after the same amount of initial data. OPNsense seems to stop forwarding the TCP packets.
Has anybody an idea why this happens?
regards,
Thomas
