Home multi-functional Router Security Network

A home multi-functional router must meet the following characteristics to be considered a good router. The first is security, the second is the speed problem, and the last is other functions. In the next section, you will learn about the common configurations of the home multi-functional router.

Home multi-functional Router Security Network

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 of interest to some netizens, because everyone thinks that a vro can access the Internet at the same time as long as it can implement multiple machines. Other functions are attached, and it doesn't matter if there are any other functions.

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 home multi-function router, which can greatly improve the network utilization and security. Next, let's talk about the functions of current home routers. 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 function is generally enabled by default for home multi-functional routers. If not, we recommend that you open it on the management interface, in this way, the computer connected to the home multi-functional router can use the network settings to automatically obtain the IP settings to access the Internet, 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 of different network segments, changing the IP address may cause application interruption.
◆ 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 PC machines 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:
◆ Multiplayer online games such as Warcraft)
◆ P2P connections such as BT download)
◆ Real-time communication, such as MSN voice and file transmission)
◆ Remote Assistance to Windows XP)

Firewall functions

This function is easy to use. In fact, the firewall function of the home multi-functional router is simple. It can only mask internal network IP addresses, freely set IP addresses, and filter communication ports. 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.

Currently, the firewall function of the home multi-functional router mainly includes anti-IP address filtering, URL filtering, MAC address filtering, binding of IP addresses to MAC addresses, anti-Black capabilities, and security logs. With the built-in firewall function of the vro, 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.
