What is intranet penetration?
First of all, the network in our life can be divided into internal network and external network in terms of application;
The intranet is your own network environment, which you can access, such as localhost for your local test;
The extranet is self-evident. When you look at webpages, videos, etc., these URLs are all extranets.
So what is intranet penetration? To put it simply, it is by accessing an external network address and then penetrating to your internal network address.
Intranet penetration is also called port mapping. In the simplest terms, it is: map the private network connected to your computer to the public network, and others can access your local services through the domain name or ip you give.
