UTM SG135 managing guests traffic accessing wifi

I hope somebody is available to help.  Not getting many replies!

OK, I have set the QoS settings and throttling and in spite of all this the traffic is maxing out ant the capacity of our broadband service provider.  What am I doing wrong please and how can I diagnose problem and fix it please?

Hello,

Thanks for reaching out to Sophos Community.

Coud you show your Qos configuration? and what is your expected result out of it? could you also share the results of your testing? May you confirm how and where do you test your configuration? Thank you 

Regards,

Hi Raphael and thanks for getting back to me.  I would be happy to share; not sure which is best way so will try screenshots.

This is my guest interface and next is my Traffic selector:-

Here is my Bandwidth Pool for Guest and Download Throttling:-

As you can see I am not too familar with taking screenshots but I hope this can be a start.

Hello, 

Thank you for your response. Could you confirm if I understand correctly what you're trying to achieve that you want a guest users to have a maximum of 4096kb / 4mb only? 

If yes, could you try using Bandwidth pools? https://docs.sophos.com/nsg/sophos-utm/utm/9.717/help/en-us/Content/utm/utmAdminGuide/RoutingQoSBandwidthPools.htm

Then set 4096 for Bandwidth and upper bandwidth limit. This configuration would specify an amount of bandwidth that the UTM won't use for any other service. Then If the traffic that matches the traffic selector needs more bandwidth, it will get more bandwidth, unless you set an upper limit. That being, we are setting an upper bandwidth limit of 4096 as per your requirement. 

Also, you may try to remove your Throttling configuration as the Bandwidth Pool configuration would suffice the requirement. 

Hope this helps.

Regards.

Hi, Did you see my screenshots?  I thought they show what you propose but the device is not working.  Can you help.

Hi, My problem is that the settings I was shwoing did not work.  If I set the direction the other way round, ie. the Source as the WAN and the Destination as the Guest network the system seems to work.  Why is that and which way round should I have it.

Finally can you please confirm that every client on the Guest network can enjoy 4Mb.  I am concerned that I can only see that one user is connected.
