hey guys!!!! do you have any knowledge on how to create codes for firewalling using C++ or C language?????

i need codes, i mean i need help on how to create an ip tracer and blocker... i have to program it.

Could you please help us on how to make a program that will trace & block IP Address of a website. Problem scenario: On a local network the server will monitor all the sites that is being visited by a client computer.... The application must automatically blocks any unlawful sites and scan the content. At the same time it will be updated with the new sites. The administrator can also use keywords to block a website such as download & electronic chat. Thanks :), email add: lady_weng18@yahoo.com, ronessa_2004@yahoo.com
