How does an HTTP server distinguish between the request received from computers behind one router?by techsin101 on March 5, 2013
Q: How does Http server distinguish between the request received from computers behind one router?
HttpServer operates on port 80. It receives and send only at port 80.
Computers behind the routers have local ip address which only works in local area network. This happens because it allow more computer to connect to internet. Allowing 1 public ip address which is usually given by ISP to be used by many. The way NAT routers distinguish between incoming data that which computer it belongs to behind it is by assigining a port to local ip address and saving this information. So if it sends something at ip 188.8.131.52 it puts port with it.
But the conflict is here:
Http Server listens to port 80.
Yet Routers must use random ports to distinguish among computers connected to it.
So what am i missing.
