Bandwidth Limit Out Per User

AaronJohnston

I'm looking for a way to limit outbound client traffic based on application (Eg. CIFS/SMB).  I do see this in the QoS bandwidth pools section, but not sure how to select traffic if I want to set a limit for each connection rather than setting a global limit on a interface or subnet?  So I want to limit file transfer speeds over my WAN interface to clients, but only for each client connection not just putting a cap on all CIFS traffic in general.  Is this possible?  How would I define this?

    Hi, Aaron, and welcome to the UTM Community!

    To do this, put a Download Throttling rule on the Internal interface to 'Limit: Each source/destination' for traffic 'Internal (Network) -> CIFS -> Internet'.  If, for example, you want to exempt yourself from this limitation, arrange to have a fixed IP and add a rule above the previous suggestion limiting you to a gigabit.

    Is that what you wanted?

    Cheers - Bob

      Thanks!

      I'm more speaking on how to classify source if I want to limit bandwidth per user/connection?  I can't put in single IP's at 1000s of users in our organization obviously.  If I add a subnet source, then the bandwidth restriction would encompass the entire subnet correct?  I want the bandwidth limit to represent a single connection/user rather than an entire subnet or site.

      Example:

      User A initiates file transfer from PC to file server - I would like to limit this transfer to 10 Mbps

      User B initiates file transfer from PC to file server - I would like to limit this transfer to 10 Mbps

      - I want to limit bandwidth for each of these without needing to create separate individual rules per user.

      I might misunderstanding the terminology here, but yes I would like to just create a rule with source subnet - CIFS - destination file server but I don't want to limit CIFS to 10 Mbps for the entire subnet, I want to limit 10 Mbps per connection in that subnet.  Hope that makes sense.

        If I understood what you're asking for, I believe that my recommendation does just what you want with the least effort.  The trick is the selection of 'Limit: Each source/destination'.

          Helps if I read correctly.  My apologies.  Yes that's exactly the setting I'm looking for!  I will give it a go in test and see how it goes.  Thanks so much.
