Wireless Connection Sharing

Hey guys,I have a wireless USB adapter installed in my computer. I get WiFi connection from my ISP. now I wanna share that connection through LAN. its not just sharing but I want to make a connection so that others can connect and register using VPN connection in my comp. I have some 4 clients connected through one ACORP switch (hub). I have got 1 LAN interface card, wireless USB adapter, 1 switch. in my switch others are also connected whom I may not want to give internet connection. if they want, they have to register account user name and password at me. I hope you understand this problem. I tried installing WinGate but setting it up is damn difficult. so Windows ICS would be a better option to share if you give some hint.thanks in advance

You can try this:1. Configure windows DHCP server to bind IP to MAC Addresses[Now you know which IPs should receive internet and which ones should not]2. Block incoming IP packets from any IP that you do not want to connect to internetDeos that solve your problem?
