Ok, I have a very weak understanding of NAT. I know what it is and does, but how does that router know which internal IP is connected to which external IP ? ie: 192.168.10.1 and 192.168.10.2 are connected to the internet. 192.168.10.1 sneds a SYN to 66.55.44.33 and 192.168.10.2 sends a SYN to 99.88.77.66. How does NAT know which is going to which. Also, How do I connect to a computer behind a NAT enabled Router ?
