UTM SG135 managing guests traffic accessing wifi

I am having to revisit this question and seek further guidance please.

I have enabled QoS on the relevant guest subnet but I need help with traffic selection. 

I have named the traffic "guests downloading"  with the guest network as the source, the service any and the destination the WAN.

For the bandwidth pool I have selected the bandwidth (4000) and upper bandwidth of 4000 and enabled the Guest downloading traffic but I am stuck when I get to Download Throttling.  I seem to have two entries enabled.  Why is that?

Also please advise if I have it right so that each guests can get up to 4096kb/s or have I in error set the total pool as 4096?  I have 40Mb/s available for the broadband connection.

Please could somebody look over this and correct me where I am wrong.

  • 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.
