UDP performance Issue with SG-1000

Greenwood2017

Hi,

I am doing some test with the SG-1000 and i have network packet lost when testing with IPerf… Everything is fine with TCP but i have errors with UDP even with a tiny small packet... I have a wireshark trace that show the lost passing throught the SG-1000 versus a port mirror not going through the Firewall to compare....

Is there some optimization possible or more testing i could do. Is somebody allready expericens some issues with UDP Packet with the SG-1000 ?

I joined 2 screenshots...

Thx in advance..

Thx for you answer, so i see that it works on your side. Were you using UDP Packets… My PFSense as only one rule (Any-Any) and is a NAT with some port forwarding... Do you think that could be the problem ?
