Hi Everyone,
Quick question for any network protocol gurus who don't mind coaching a newb. I'm struggling trying to understand the routing of packet traffic when two or more computers share one ISP through a DSL router. Allow me to explain:
1. Hypothetical situation: two computers on a DSL router, both sharing one Internet connection. The router has IP address 128.128.128.128 (I don't know if this is a legal IP, and it doesn't matter. Please bear with me.). The first computer has IP address 10.0.0.1, and the second computer has IP address 10.0.0.2.
2. When 10.0.0.1 sends packets to a server (let's say 255.255.255.255), they are recoded by the router as coming from source IP 128.128.128.128. The server receiving the packets then responds to 128.128.128.128 with its own packets.
3. The router receives packets emerging from source 255.255.255.255, targeted for 128.128.128.128. How does the router software determine where to send the packets? It can send them to 10.0.0.1, or 10.0.0.2. What gives?
If anyone can point out what I'm missing here, it will be sincerely appreciated.
