I'm sure I'm missing something, I have read the various sections but nothing I do seems

to have an impact one way or another, I'm trying to limit bandwidth in 5,10,20 and 40mbps chunks, below a snapshot of my BWM config.

IP's used are Public IP's no SNAT, below the text of the relevant part of the config for ease.

http://bwm 1 description Media_download destination VM_download.cfts.co log inbound guarantee-bandwidth 20000 priority 4 outbound guarantee-bandwidth 20000 priority 4 inbound ceiling maximize-bandwidth-usage outbound ceiling maximize-bandwidth-usage ! bwm 2 description Media_download source VM_download.cfts.co log inbound guarantee-bandwidth 20000 priority 6 outbound guarantee-bandwidth 20000 priority 6 inbound ceiling maximize-bandwidth-usage outbound ceiling maximize-bandwidth-usage ! bwm 3 description Mallicard Public facing VPS_in destination VPS_Malicard_UI log inbound guarantee-bandwidth 20000 priority 7 outbound guarantee-bandwidth 20000 priority 7 ! bwm 4 description Mallicard Public facing VPS_out source VPS_Malicard_UI log inbound guarantee-bandwidth 20000 priority 7 outbound guarantee-bandwidth 2000 priority 7 ! bwm 5 description Spe Bookings VPS_in destination VPS_Spe_Bookings log inbound guarantee-bandwidth 5000 priority 7 outbound guarantee-bandwidth 5000 priority 7 outbound ceiling 10000 ! bwm 6 description Spe Bookings VPS_out source VPS_Spe_Bookings log inbound guarantee-bandwidth 5000 priority 7 outbound guarantee-bandwidth 5000 priority 7 inbound ceiling 10000 outbound ceiling 10000 !

Be good to know what I've missed, if you need more information let me know.

    It is recommend to limit with correct incoming interface and outgoing interface then any like incoming LAN/DMZ to outgoing WAN

    It would help to know the IP's or do you mean your LAN IP's are not rfc1918?

    Test without source/destination.

    Is maximum box set? not just inbound out outbound

    I also recommend enabling this option by SSH
    configure terminal
    bwm control-tcp-ack
    write

    Hi @peter2cfts,

    Regarding your problem, please make sure to uncheck Maximize Bandwidth Usage.

    In addition, if the initiating side of the download session is VM_download or VPS_Malicard, then it is correct to configure the source as VM_download or VPS_Malicard, just like in the 2nd, 4th, and 6th rules shown in your screenshot.

    If you have already verified these settings and the issue still persists, could you please provide more details about your application scenario, along with a scenario diagram or related information? This will help us better assist you.

    These are unchecked for all but one.

    USG700-BWM-Detail.png

    [Public IP]>Flex700(Not NATed)>ISP Switch(vlan)>ESXi-HOST>ESXI Switch>VM [Public IP]

    Does this help.

    For rate limiting you need to set maximum boxes the the  inbound out outbound boxes are guarantee settings

    Current BWM settings

    image.png

    Still seems to make no impact changing the max bandwidth

    So I guess we may need to got back to basics

    I have as a test link 100Mpbs which I believe = 100000 kilobytes per second (kbps) is that correct?

    How are you testing to see if its limiting?

     100000 kilobytes per second (kbps) is 97.66 Mb

    You have to understand that when limiting like from LAN to WAN your Inbound is when you make the connection out from LAN to WAN it be your download but outbound is when you make the connection out from LAN to WAN it be upload. And then you got WAN to LAN when something comes from WAN to LAN where inbound is you uploading from a connection that from WAN to LAN and outbound is you receiving from a connection that from WAN to LAN.

    Are you try to limit from one LAN subnet to another LAN subnet?
