[PLUG] Router Suggestion + Home proxy server setup

["Tharun Kumar Allu" <tharun.allu@gmail.com>]

Hi,
I am trying to setup squid proxy at home. I have 4 machines 1 linux box 3 windows connected to a D-Link router (Wired and Wireless) which connects to a DSL Modem. Currently all the machines share Internet directly from the router.
With the current hardware can I configure the following scenario.

Network of 4 machines connected to each other but not all to the internet.
Only 1 of the 4 machine is connected to the internet 
The 3 other machines use the 4th machine as a proxy server.

All machine have 1 network card each.

Is it possible with any router to just block internet access to few machines or only allow from one machine?

Thanks
Tharun
