When working in the company, use Remote Desktop to connect your home computer. Both sides of the remote desktop connection need to be in the same network, such as the same LAN or the same Internet. You can't directly control computers in another LAN from the Internet. If you want to access, you need to map the ports on the router or firewall.

But you can use computers in the local area network to control computers on the Internet. Therefore, if the controlled computer uses ADSL dial-up network to access the Internet, the IP address required by the remote desktop is the Internet IP address obtained after dialing, not the LAN IP address set by itself.

How to use the port?

Purpose of the port: The port is the outlet for the equipment to communicate with the outside world.

Ports can be divided into virtual ports and physical ports.

Virtual port refers to the port inside the computer or the switch router, which is invisible.

The role of the port:

The role in the invasion

Someone once compared the server to a house and the port to a door leading to different rooms (services), which is a good metaphor if details are not considered. If an intruder wants to occupy the house, he will definitely break into the house (physical invasion is another word), so it is very important for the intruder to know how many doors the house has opened, what kind of doors it is and what is behind them.

Intruders usually use scanners to scan the ports of the target host to determine which ports are open. From the open port, intruders can know what services the target host provides, and then guess the possible vulnerabilities. Therefore, scanning ports can help us better understand the target host. For administrators, scanning the open ports of this machine is also the first step to do a good job of security prevention.
