What cable should be connected to the wan port of the router? Must read: The difference between the wlan port and lan port of the router

php editor Xigua will explain to you the difference between the WAN port and the LAN port of the router and the correct wiring method. The WAN port of the router is generally used to connect to the Internet, while the LAN port is used to connect to local area network devices. Correct connection methods can ensure smooth network connectivity and improve network security. An in-depth understanding of this knowledge will help you better manage and maintain your home network and ensure smooth network access. Next, let us discuss in detail the difference between the WAN port and the LAN port of the router, as well as the correct wiring method.

With the increase in the number of computers in the family that need to access the Internet, many families have chosen to use broadband routers to achieve shared Internet access. However, due to a lack of understanding of network knowledge, many users have purchased broadband routers. Finally, I found that some network ports are labeled WAN and some are labeled LAN. What are these two network ports used for? What is the difference between them? How to use them better? Many friends made this mistake worry. To this end, we will work with you to understand the differences and some new ways to play these two types of network ports on broadband routers. 1. WAN stands for Wide Area Network in English, which means wide area network, while LAN stands for Local Area Network, which means local area network. It is not difficult to see from their names that the WAN port is mainly used to connect to the outside. Networks, such as ADSL, DDN, Ethernet and other access lines, while the LAN port is used to connect to the home internal network, mainly connected to switches, hubs or computers in the network. It can be said that these two types of network ports are one for external use and the other for external connections. Class within.

The WAN port and LAN port of the broadband router have different network cable connection methods. To connect the access network cable provided by the network operator, plug it into the WAN port and connect the computer sharing the Internet to the LAN port. Then, use a computer to log in to the router's management interface and perform the necessary configurations to easily complete the shared Internet settings.

In a home network, when a device wants to access the external network, it will first send the data packet to the default gateway, which is the broadband router. The router checks the internal IP address in the packet and looks for a matching entry in the NAT address translation table. Once a matching entry is found, the router uses the WAN port IP address to communicate with the external network. This process ensures that devices in the home network can securely exchange data with the external network while efficiently utilizing network resources.

4. After the external network receives the data packet, it will parse out the WAN port IP address of the router in the data packet, respond to the address, and send the response data packet to the router. Then the router performs NAT address translation again, converting the WAN port IP address to the intranet IP address for sending the request, and finally completes the entire data packet sending and receiving process.

5. In addition to improved bandwidth, most multi-WAN port routers also support fully automatic load balancing and real-time backup , and can specify priority channels based on source or destination addresses, automatically redistribute traffic in case of failures, etc. The use of multi-WAN port broadband routers can basically avoid network interruptions caused by network operators. Although purchasing multi-WAN port routers and increasing network connections Incoming lines will cause an increase in investment, but for enterprise users, the protection they receive far outweighs their costs.

6. In addition to the conventional WAN port connected to the external network home line and the LAN port connected to the intranet computer, we can also connect the home line and the computer network cable to the LAN port. There are several things worth paying attention to when using a broadband router as a switch. First, the LAN port of your broadband router or the uplink device network port needs to support the port flip (Auto MDI/MDIX) function. Otherwise, you You may need to change your direct connection cable to a crossover cable so that your broadband router can connect to the external network through the LAN port

7. Using this method will lose the routing function of the broadband router. Therefore, to achieve shared Internet access, the computers in your home network need to use the legal IP address in your operator's network. At the same time, in order to maintain access to the router, the IP address of the router's LAN port must also be set to the legal operator's address.

To put it simply, the wan port is like the door of your home. There is usually only one, which is responsible for the connection between your home and the outside. The lan port is the small door of each room in your home, which is responsible for the connection inside your home. This is also the reason why sometimes you can connect to wifi but not the Internet. There is no problem with the connection between the small doors of your house, but the main door out is broken.
