How to use security routers to manage small and medium-sized enterprise networks (1)

User management is a common problem for small and medium-sized enterprises. For example, how do I allocate a limited IP address? How do I control the Internet access permissions of different employees? How to block visitors from using the enterprise network? How do I allocate more bandwidth to executives or CEOs? Do you need professional network management software to manage these problems?

In fact, to manage networks and ensure network security, network administrators mainly manage users well. All these problems can be achieved through the user management function of routers. Here, I will introduce how to use the user management function of the security router to manage the security network of small and medium-sized enterprises. This article takes Qno xianuo Security Router as an example.

The management of Intranet users can be divided into three aspects: reasonable allocation of Intranet addresses in the enterprise LAN, addition of Intranet user control, and effective control of Intranet users. If there is no reasonable and effective management mechanism, it will bring a lot of negative impact and economic losses in network management and security.

The above internal network management can be achieved through the relevant functions of the Qno chinamoocs router, to achieve network security. The Qno na router provides dynamic IP Address Allocation and static IP Address allocation functions to meet the different needs of internal IP address allocation. The vro also provides the IP Group management function to set groups that require different Internet access permissions for different departments, facilitating unified management. Use the IP/MAC binding function to avoid network management difficulties caused by IP address abuse in internal networks. You can also use QoS settings to manage the bandwidth for Intranet users to access the Internet, ensure that enterprise leaders want to ensure smooth connection to the Internet, ensure that the company's important business information is not delayed, and that important application services are online smoothly.

IP Address Allocation

The first consideration for an enterprise is IP Address Allocation Management. Dynamic IP Address Allocation uses DHCP servers. The advantage is that clients do not need to be configured, but only need to configure servers. Static IP addresses must be configured on the client, which is relatively rigorous and fully controlled.

The Qno na router provides dynamic IP Address Allocation and static IP Address allocation functions to meet the different needs of internal IP address allocation. Qno vro provides the smart DHCP function for Dynamic IP Address allocation. It supports Class c ip addresses. You can set the IP Address allocation range and address lease time. Go to "DHCP configuration" for "DHCP function ".

Figure 1: DHCP configuration shows that the distribution range is 192.168.1.100 ~ There are 50 computers in the range of 192.168.1.49. The address lease time is 1440 minutes.

Learn about the internal network IP address allocation through "DHCP server status display, we can learn about the DHCP server and the "host name", "ip address", "MAC address", and "current lease time" of the internal network users ".

Figure 2: DHCP server status display. The vro also supports static IP Address allocation, as long as the IP address does not conflict with the DHCP range.

Static IP Address Allocation, As long as DHCP is not activated. However, the IP address configured on the client must be consistent with the vro configuration range. You can also use the DHCP function in combination with a static IP address, that is, some of the IP addresses configured in the router are issued using DHCP, and some use static IP addresses. For example, in-plant computers do not often move, but static IP addresses can be used. Business personnel computers often move, but dynamic IP addresses are used.

Proper IP Address allocation is the basis for subsequent security management. It is necessary to properly balance security and convenience.
