    Találtam még egy ilyen megoldást, de ez végképp nem megy (persze nem OpenWrt-re van):

    #!/bin/bash
    #
    # tc uses the following units when passed as a parameter.
    # kbps: Kilobytes per second
    # mbps: Megabytes per second
    # kbit: Kilobits per second
    # mbit: Megabits per second
    # bps: Bytes per second
    # Amounts of data can be specified in:
    # kb or k: Kilobytes
    # mb or m: Megabytes
    # mbit: Megabits
    # kbit: Kilobits
    # To get the byte figure from bits, divide the number by 8 bit
    #

    #
    # Name of the traffic control command.
    TC=/sbin/tc

    # The network interface we're planning on limiting bandwidth.
    IF=eth0 # Interface

    # Download limit (in mega bits)
    DNLD=1mbit # DOWNLOAD Limit

    # Upload limit (in mega bits)
    UPLD=1mbit # UPLOAD Limit

    # IP address of the machine we are controlling
    IP=216.3.128.12 # Host IP

    # Filter options for limiting the intended interface.
    U32="$TC filter add dev $IF protocol ip parent 1:0 prio 1 u32"

    start() {

    # We'll use Hierarchical Token Bucket (HTB) to shape bandwidth.
    # For detailed configuration options, please consult Linux man
    # page.

    $TC qdisc add dev $IF root handle 1: htb default 30
    $TC class add dev $IF parent 1: classid 1:1 htb rate $DNLD
    $TC class add dev $IF parent 1: classid 1:2 htb rate $UPLD
    $U32 match ip dst $IP/32 flowid 1:1
    $U32 match ip src $IP/32 flowid 1:2

    # The first line creates the root qdisc, and the next two lines
    # create two child qdisc that are to be used to shape download
    # and upload bandwidth.
    #
    # The 4th and 5th line creates the filter to match the interface.
    # The 'dst' IP address is used to limit download speed, and the
    # 'src' IP address is used to limit upload speed.

    }

    stop() {

    # Stop the bandwidth shaping.
    $TC qdisc del dev $IF root

    }

    restart() {

    # Self-explanatory.
    stop
    sleep 1
    start

    }

    show() {

    # Display status of traffic control status.
    $TC -s qdisc ls dev $IF

    }

    case "$1" in

    start)

    echo -n "Starting bandwidth shaping: "
    start
    echo "done"
    ;;

    stop)

    echo -n "Stopping bandwidth shaping: "
    stop
    echo "done"
    ;;

    restart)

    echo -n "Restarting bandwidth shaping: "
    restart
    echo "done"
    ;;

    show)

    echo "Bandwidth shaping status for $IF:"
    show
    echo ""
    ;;

    *)

    pwd=$(pwd)
    echo "Usage: tc.bash {start|stop|restart|show}"
    ;;

    esac

    exit 0

    Egész életemben azon gondolkodtam, hogy kéne valamit dolgoznom. Ezért aztán a végén nem is maradt rá időm.
