I have two lan cards in my Server in such a way that Lan Card a1 is connected to internet and holds Public IP infomration and Lan card a2 is meant for private internal network and holds internal IP information and connects to client machines in my internal network.


In my coding, I want to develop a module that can enable me to find realtime IP addresses and/or computer name of the Client machines that are using internet via server in my internal network.

I need Source code or example(for windows).
