Sorry if my question is not so sophisticated, but so is my knowledge in
networking...
1. Suppose one thread in my win32 application communicate with some other
party across the internet in ip1:port1 and I want some other thread to
communicate with another party(another ip address) in the same ip:port
(ip1:port1). Is that possible?
Sure, in connection which have characterize by IP/ port pair of source and
destination and protocol something have being different. And that in your
case IP of remote.
2. My UPNP nat router informs my application about the outer IP:PORT that
are opened for my application. Can my application use the corresponding
inner IP:PORT to communicate with another PC on the internet?


That what IE do e.g. It doesn't know about router existance
