    Excellent stuff.

    You don't need a gateway address for this interface (leave it blank).

    How are the Windows machines getting their IP addresses? You will need
    to set these to 192.168.0.2, 192.168.0.3 etc. Their gateway address is
    192.168.0.1.

    They also need access to a DNS server. To get things working, use the
    values for your ISP's server (you should these on the Linux box in
    /etc/resolv.conf).

    You also need to tell the Linux PC to forward IP packets:
    Put "net.ipv4.ip_forward = 1" in /etc/sysctl.conf
    To save rebooting, also do "echo 1 > /proc/sys/net/ipv4/ip_forward" as root.

    You will also need to configure NAT:
    iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE

    (Change eth0 to whatever your ethernet card is).

    Once you've got this working you can then look at setting up DHCP for
    your internal network along with a DNS server so that the internal
    Windows machines are not tied to the ISP configuration. But you can
    leave that for another day.
