I've been doing research on Port forwarding, or "internal network penetration" for a while , which is a technique used to make services or data from an internal network accessible on the internet. It's commonly used in scenarios where you need to access resources in an internal network from outside the network, such as remote control or file transfer. I've practised a lot, but I kinda worry about its potential security issues.
