    I'm on 'Kabel Deutschland' and get about a zillion ARP requests
    a day, sometimes this even f**ks up the cable modem (EPC3212).
    I usually just 'reboot' the modem then....

  2. I find this rule strange. Did you get it from any standard cookbook?
    It will necessitate connection tracking for any packet routed back to
    your LAN. It's quite improbable that this can account for 100ms
    delay, but could you just as an experiment replace this by:

    iptables -A FORWARD -i wan0 -o eth0 -j ACCEPT
