I've got a Windows 2003 Server setup at home and its connected to a gigabit switch. On that switch, an adsl modem router, wireless router and 2 workstations are connected to it. On the wireless router, 2 computers are connected to it. I want to be able to filter / block a workstation from going to the internet. How am i able to do it? I have specify the firewall settings on my adsl router not to allow eg 10.0.1.11 to access the intenet but it doesn't work. How do i go about resolving it ? Thanks.
