How To Determine Source of Outbound Traffic

busthead

The outbound interface of my Internet uplink is being saturated. How do I determine which host on my LAN is consuming the minimal throughput allotment from my ISP?

    Hi Busthead,

    You should enable "Network visibility" under Web Protection / Application Control. The you can launch the "Flow Monitor" to view the connections nearly realtime.

    With "Logging & Reporting / Network Usage" Tab Bandwith Usage you should see the most consuming IP's (Firewall). If the client uses your proxy then you will find the reports under the web protection subsection.

     

    Good luck!

    I believe iCloud backups from iOS devices are consuming my outbound throughput allotment.

    If anyone has had success throttling outbound traffic to Apple's iCloud backup servers, please share your QoS config.

    Thx
