Low flow

Hi lauwiks Cutman,

Thank you for reaching out to the Community! 

Are there any errors on the interface (ifconfig)? Did you configure interface speed manually or automatically? 

How are you testing the speed? Did you use any advanced filtering on your firewall rules? 

Thanks,

Hello patel
Thank you for having responded to my message.

Sorry I took a long time to answer you but I had to do some test.
To be sure that it is the sophos XG home that is causing me a problem

I have done several flow tests with iperf3 from my internal network

The server is my nas synology and the client is my laptop

If my nas and my laptop are on the same subnet, no flow concerns
The problem occurs when the two devices are not on the same subnet (VLAN)

At first I thought that the problem could be my switch but he is not the cause.

I connected my laptop and my sophos XG Home directly by cable
And I still have a reduced flow.

I hope I was clear enough

Hi,

please post a copy of your firewall rule.

Ian

This rule is for the iperf test 

the server list are on this link 

iPerf - Serveurs iPerf3 public

Hi,

while I can't understand the values in your rule, I suspect that you are hitting the DPI.

Try enabling the web proxy, just tick the box and test again.

Ian

Thank you for your feedback but what do you mean by web proxy .

The service is well activated.

And the DPI is not only reserved for XG 18?

Hi lauwiks Cutman,

Thank you for the update. 

Did you notice any interface level drops or errors? You can check these from the Advanced shell and running the "ifconfig" command.

Thanks, 

there are indeed packet drops.

I have the impression that I will have to do a factory restore and submit an export.

I hope this will solve my problem

Finally the factory restore then the import of my backup did not solve my problem.
It even made me delete my rule groups
Moreover I cannot even reinstall to zero because version 17.5.15 is not available
