  1. I assume you’re configured as follows (and using ICS for your gateway):

    [modem]<-- wire -->[pc (gateway)]<-- wire -->[switch]< -- wire -->[pc]

    And now want to limit access to the Internet based on IP address.

    IIRC, the Windows firewall doesn't provide this kind of filtering, but many third party firewalls certainly do (e.g., AVG). In fact, it would probably be more effective to limit access based on MAC address (a bit easier for IPs to be manipulated than MAC addresses, but ultimately both are vulnerable to being altered by end users).

    Frankly, I’m not sure why you wouldn’t just use a router and manage its firewall to limit access. You could then use DHCP to control IP assignments as well rather than deal w/ manual TCP/IP configurations.
