With the development of China's routing industry, the application of broadband routers is more extensive. Here we mainly explain the various functions of broadband routers. It is estimated that many family Internet users will encounter a problem of multi-host internet access with a network cable. the most suitable solution to this problem is undoubtedly the purchase of a Broadband Router with a low price and many functions, many products also provide basic firewall functions.
So what functions should a Broadband Router suitable for shared Internet access at home have? In fact, this problem is rarely concerned by users, because everyone thinks that as long as a Broadband Router can achieve simultaneous Internet access on multiple hosts, other functions are attached, it doesn't matter. As a matter of fact, most of the current Broadband Router functions are already very powerful, and many functions are indeed very practical for general home users, which can improve the performance of many network applications, learn more about the additional functions provided by the Broadband Router, which can improve the network utilization and security. Next we will talk about the functions of the current home Broadband Router. By the way, we will tell you which functions are more practical and which functions are of little significance:
DHCP Function
This function is one of the essential basic functions. It is implemented through a server in a network to provide the corresponding network configuration service, you can provide temporary IP addresses, default gateways, DNS servers, and other network configurations for network terminal devices. This feature is generally enabled by default. If not, we recommend that you enable it on the management interface, in this way, the computer connected to the Broadband Router can access the Internet using the automatically obtained IP settings in the network settings, which is very convenient. Of course, DHCP technology also has its disadvantages:
Random IP Address: users' IP addresses are randomly allocated with uncertainty.
Access permission change: if a user's access permission is divided based on an IP address, the access permission varies with the IP address.
Inaccessible: IP addresses obtained through DHCP are uncertain, making it difficult for users to be accessed.
Application continuity: If you use networks continuously between WLAN networks in different network segments, changing the IP address will interrupt the application.
Poor security: external network users pose security threats to the network itself
UPNP Function
Universal plug-and-play (UPnP) is a common architecture for peer-to-peer network connection between PCs and smart devices or instruments, especially in the home. UPnP is based on Internet standards and technologies such as TCP/IP, HTTP, and XML, so that such devices can automatically connect to and work with each other, so that the network, especially the home network) it is possible for more people.
The UPnP is widely used because it targets home networks, nearby networks, and networks in small businesses and residential buildings. Under the management of network control devices, it supports data communication between any two devices. UPnP does not depend on a specific operating system, programming language, or physical media. This is not easy to understand, because it requires additional NAT and programming knowledge to be clearly explained, so we can simply understand it in this way, UPNP allows Intranet users to implement the following applications:
Multi-player online games, such as Warcraft and other multiplayer Combat Games)
P2P connections, such as BT downloading)
Real-time communication, such as MSN voice and file transmission)
One of the functions of Remote Assistance in Windows XP)
Firewall functions
This function is easy to use. In fact, the firewall function of the home Broadband Router is simple. It can only mask the internal network IP address, freely set the IP address, and filter the communication port. In addition, the filtering rules of household servers are only some basic data packet rejection rules, and cannot achieve good protection effect. However, they can still cope with General cyberattacks.
The current features of the Broadband Router firewall include anti-IP address filtering, URL filtering, MAC address filtering, binding IP addresses to MAC addresses, anti-Black capabilities, and security logs. With the built-in firewall function of the Broadband Router, you can set different filtering rules to filter abnormal information packets from the Internet. In addition, if the vro enables the firewall function or the firewall's filtering rules are too strict, some normal network applications may encounter errors, however, you can enable the firewall in most cases.
