  • Heavy Upload Traffice

    From last Saturday our EFW is showing heavy and constant upload traffic. Please look at the enclosed graph.



    from this day (Sat) our internet has become very slow and the bandwidth utilization of our internet connection Uplink is always 100% also we don't have any known user doing any heavy uploads.

    How can we identity where is the problem?

    Have you tried looking at logs or interface statistics on any other down stream devices (routers, or switches)? If you can post a basic network diagram we may be able to help further.

        That's about 1.6Mbps. You'll want to put a traffic monitor (like MRTG or PRTG) on your switch and monitor the traffic on each port to see what port this is originating from, then you can look at the computer connected to that port.

          What kind of network switch do you have? In many instances, if it's a managed switch, it will have statistics for each port. Just search for the one with a suspiciously hight amount of bytes going out.

          Once you get this mess straightened out, then you can put some kind of network analyzer on the LAN.

          Let us know what you find! Now you've got me curious.


          BTW, bonus points for the ASCII diagram.
