Speaking of port mapping, first talk about nat. Simply put, nat is to use the internal address in the internal network of the LAN, and when the internal node wants to communicate with the external network, it replaces the internal address with a public address at the gateway, so that it can be used normally on the external public network (internet). Using nat, multiple computers can share the Internet connection. This function solves the problem of shortage of public IP addresses. Through this method, you can only apply for a legal IP address, and connect the computers in the entire LAN to the Internet.
Port mapping is often said to be a kind of NAT. Its function is to translate the address on the public network into a private address. The ADSL broadband router with routing mode has a dynamic or fixed public network IP. ADSL is directly connected to the HUB or switch On, all computers share the Internet.
Port mapping software can be said to be one of the most popular and influential tools in the Internet field in recent years. By connecting the network devices in the local area network with the external network, it has achieved many amazing functions and changed people's lives in many ways. If you have a good brand, please choose to quickly analyze it. It is said to be very good.
What can port mapping software do? For example, quick analysis. In a computer network, each network device has one or more ports, which can not only receive receipts, but also send them. Quick Analysis can establish a port mapping method so that internal devices can receive access requests from the external network. So as to realize the function of remote access. This means that we can connect to the company's internal server, home network equipment, or other equipment with port mapping software installed through the Internet to realize the convenience of remote control and access.
1. It changed the way home networks are used. In the past, control and management of home network devices was often limited to within the home. However, with port mapping software, we can achieve remote control and management by remotely accessing home network devices, such as routers, smart home devices, etc. Whether it is helping family members solve network problems, or remotely monitoring the security situation of the family when they are out, it has become more convenient and easier.
2. It changes the way telecommuting works. In the past, accessing servers or other resources within a company remotely while away from the office required complex VPN or special network settings. Now, with the port mapping software, you only need to simply set up the port mapping, and you can remotely access the internal resources of the company from anywhere through the Internet, effectively improving the flexibility and efficiency of work.
3. It promotes the development of cloud computing and the Internet of Things. By simply configuring port mapping, after connecting the device to the cloud server, the data can be stored. At the same time, network devices can also be connected to the Internet through port mapping software to realize innovation and development in smart home, smart city and other fields. Port mapping software provides a low-cost and high-efficiency connection method for the development of cloud computing and the Internet of Things, allowing people to enjoy more convenience brought by intelligence and digitalization.
Quick Analysis How to set up port mapping to achieve intranet penetration?
1. Go to the Kuaiyan official website to download the Kuaiyan client and install it; or search for "Kuaiyan" on Baidu and enter the official website to download the software;
2. Log in to the quick analysis client and enter the web management page;
3. Click on the client, after logging in normally, click the "Add Mapping" icon in the upper left corner, and the port mapping setting window will pop up;
4. Fill in the port mapping information. Customize the application name, the host is the ip address of the internal network host, select the port open to the outside world, and click OK to complete the information filling;
5. After the port mapping is added, an address that can be accessed by the external network is generated, and the port mapping is completed;
6. Test. Enter this address in the browser on the external network to access the service application built by the internal network host, and the NAT penetration is successful.
To sum up, the changes of port mapping software in remote office, home network and cloud computing Internet of Things are obvious. It not only greatly improves the convenience and efficiency of remote access, but also promotes the development of cloud computing and the Internet of Things. As an innovative tool, port mapping software still has great potential and room for development, and we can expect it to play an increasingly important role in future development.
