    I have a interessting question:
    I have a FreeCom Classic SL Network Storage device in my network and when I extended my network using a second router, I found, that this hard disk creates about 40kB traffic every minute.
    Now I ask myself: Does this traffic also leaves my network and creates online costs (cause I don't have a flat rate but only 2GB per month). through the router, which it is attached to DSL modem?

    Best regards

    DSL modem
    ~SiteCom Router
    |~Router, that finds constant traffic at its Uplink

    What kind of traffic is it? Probably broadcast traffic? If so then it should be dropped before it gets to your modem.

    Probably yes, but how can I know? Why do you think, that a broadcast would not go beyond the router?

    By looking at the destination address of the traffic. The broadcast address is based on the subnet mask but usually is something like

    The FF:FF:FF:FF:FF:FF MAC address is a broadcast address as well.

    Because one of the purposes of a router is to breakup broadcast domains. ;)
