    I think it would be good for you to have your box connected to the
    internet first. For my box i have two network cards, one is connected to
    the dsl model (eth0) and 2nd is to a hub for internet network (eth1).

    eth0 should use the gateway and ip that is provided by your provider
    eth1 should be 192.168.x.x. for ip I use 192.168.1.1 and gateway should
    be the same as eth0. Get eth0 to connect to world before you do your lan.
    To get lan going you will need to configure routing and firewall for
    masquerading.
