    Hello all,

    I got a few responses in the meanwhile but nothing did the trick so
    far. I have changed the ip-address an plumbed up the device. I have
    added a default route and can access the machine through the external
    interface. But the guy is not routing, inspite of

            /usr/sbin/ndd -set /dev/tcp ip_forwarding 1
            /etc/init.d/inetinit start
            /etc/init.d/inetsvc start

    And yes, in.routed is running. I even killed this guy and started it
    manually again. No way. Any more ideas?

    Thanks a lot!

    Regards,

       Andreas
