I have two networked computers that are both running windows vista. I share my internet connection by connecting my dsl modem to my wireless router. One of my computers connects to the router with an ethernet cable and the other wirelessly. The internet and lan work fine, but I want to be able have both computers connect to the internet through the router but not to each other. Is there any way I can prevent the computers from creating a lan with each other but still allow both to access the internet?
