 Posted: Mon Aug 20, 2007 1:38 am Post subject: NAT ~ when two computers with same IP talk? |
 |
|
What happens when I'm at home behind my router at 192.168.0.1 and I
talk to my friend who's at home behind his router also using the IP
address 192.168.0.1. I'm rusty on NAT, how does my router know its
sending outwards instead of to itself?
Could anyone briefly describe the process NAT uses in this situation? |

First, you are using your friends 'external' address as the
destination, as your box would not send any traffic off your segment
unless that is the case. Second, your router basically changes the
source of the packets to its own public interface, and then sends to
the destination. His router is forwarding ports or whatever to get
the unrequested traffic forwarded to his box, but the replies from his
side will use the same NAT technology to manipulate the source of the
packets. Nothing more complicated than that..... |
