    File: /etc/networkinterfaces

    # This file describes the network interfaces available on your system
    # and how to activate them. For more information, see interfaces(5).

    # The loopback network interface

    auto lo
    iface lo inet loopback

    auto eth0
    iface eth0 inet dhcp

    auto eth1
    iface eth1 inet dhcp

    On which of the network interfaces are you unable to connect (eth0 or eth1)?

    I'm not sure but i think the Broadcast at eth1 has to be 194.54.47.255

    You can use http://subnetmask.info/ to check if the settings for eth1 are ok.

    Also, have you tried to connect from within your local network and from the outside?
