So the router stamps it with a ticket, says it is packet 1200, computer 192.168.100.1, inet address 64.156.243.1 and when it get a reply from a website the packet is stamped the same, so it can go back to your computer. If you have two computers on your network, the difference will be that it will be packet say 1401, computer 192.168.100.2 and same inet add. But because the packet has a header that says that, it will be known where to send it. In order for your router to do that it uses an ethernet addressing scheme, and each computer has a 'mac address' to its ethernet card that helps it find it on the net.
