I get the idea that my router uses DHCP to assign IP addresses to the computers on my local network and the router gets an IP address using DHCP from the ISP which it uses as its address when it communicates with the ISP.
As I understand the situation a computer on the local network will send a message to the router with the address of the site it wants to communicate with. The router will then pass that message into the internet and it will eventually be transferred to the desired web site that will respond by sending data addressed to my router.
OK, but when that data gets back to the router how does the router know which computer on the local network to address the message to? Is it just based on fact that the router knows which guy on his local network sent data to a particular address so that when data comes back from that address the router knows where to send it? It seems like there might be problems with this method if two computers on a local network request data from the same server in a similar time frame.
