I'm trying to do this web content filtering at a small elementery school and is tending to be somewhat difficult to implement since I'm already blocking some ip address from accessing the Internet and allowing others. Now, I have no idea how I can filter only a hand full of the allowed ip addresses. Don't know exactly how to do it since there isn't any if statements and stuff like that to use for the ip addresses I need filtering for. Please guide me to where I can get an idea of what to do in my case. I appreciate yout time.
