PC01 - PC02 -- ROUTER -- PC03 - PC04 You can stop PC01 and PC02 from seeing PC03 and PC04 packets. And vice versa. You can not stop PC01 seeing PC02 packets. PC01 and PC02 will see netbios broadcasts, will send and receive udp name resolution, will use TCP 139 for transfers. You can not stop the packets appearing on the left side of the diagram with your router. You can only stop forwarding them from left to right side. Regards, Maciek
