Hello folks,
What can you send to an external ip address that is behind a firewall and a router? Is that even possible? If so how?
I said no cuz for me to be able to send somethn to a machine, I need a port beside the IP address and without knowing or having a specific port, I don't see how one can easily be able to communicate with my machine without of course exploiting or hacking to my system. I am not talking about hacking here. I am asking about using a single external IP address if you can send something to a pc? If you say yes...let me hear you, if you say No then we are on the same page.
Any idea?
