How to Bypass NAT Through WebRTS?

Question

Computer networks

Recently I became interested in hacking a PC by IP. Faced such problem as NAT which replaces the IP Address. After a little digging, I found a vulnerability through the browser that shines the local IP. Using WebRTC, you can automatically establish a direct peer-to-peer connection with the client, even if the client is connected via VPN. A side effect of this convenience is that the client automatically and without warning gives out its internal IP address.
How can I push the code that shines IP and get access to the PC?
PS Here is the link I found

Answer 1

Nuok, did you find out the internal IP 192.168.1.2 and what will you do with it? Without editing the NAT table, you won't be able to do anything.

Answer 2

Finding out the internal IP is, of course, cool :) but what's the point of it? Here, I have an internal IP : 10.50.1.1 - try it, get access :D
