    Hello All,
    I have a Win 2003 server machine that is my gateway (has 2 network cards:
    INTERNAL and EXTERNAL) . The office network is connected to the internet
    through this server (through NAT). I am trying to change the firewall rules
    so that certain computers (with internal IPs) are blocked from using the
    internet but I can't seem to do so. When I change the firewall rules on the
    EXTERNAL to deny access to an internal IP, it does not work.
    Any ideas ?
