    Hi

    i did run the systen half an hour without ppp . there was no badness in
    the logs
    in the time.

    after after starting the internet without the firewall the messages about the
    badness were after a few minutes in the log.

    so the bug is not in the iptables code.

    it might be in the pppd driver .

    I use pppoe (ADSL) using the userspace pppoe driver.

    On my old Installation I used the kernel space driver , were the badness also
    also was.

    my ethernet driver is 8139too
    I use pppd 2.4.3
