Internet&LAN

I have a local area network with some computers and different OS (Win98, WinXP, Win2000, WinMe) using the Microsoft Net client and TCP/IP protocol.

The conexion with internet is made with a DSL Router.

Every computer has connection to Internet, however, How can I make certain computers to have access to the LAN only but not to have access to Interntet?

In other words I have A,B,C,D,E computers in the LAN. I want everyone to have access to the shared files of the others but only A and B to have access to Internet.

Is your network set up using ICS, hub, switch or router. That informaton would be of help.

there should be a way to limit internet access by machine in the router setup. what router do you have?

Missed that. :(

Check you manual for IP Filtering, that should do it I believe.

All computers are switched to a HUB and the router is also switched to it, however is not directly connected to any computer.

How can I do the IP filtering? Should I connect the router to a computer and configure it this way?

Most likely the DSL router is set as the gateway on TCP/IP settings. Using static IP's and removing the default gateway from the non-internet PC's should do the trick.
