    Here is the output of a tracert run from my windows workstation behind my Debian
    Box (my other box didn't have traceroute) I had to ping the IP of google because
    I can't resolve domain names either.

    The Ping command has been running for about 10 minutes now without any result,
    not even a timeout...

    Here is the output of the sysctl command on my Debian Box:
