Other functions of the Broadband Router

China's broadband routers have developed rapidly and have excellent functions. Here we mainly introduce DMZ hosts and virtual servers, including how to enable DMZ in the Broadband Router and how to create virtual servers. How can I make the best use of my purchased products? Is to make full use of all its functions. For those of us who frequently access the Internet and have more than one computer at home or in the company, the Broadband Router is very important.

However, when purchasing and using a Broadband Router, many of our users only pay attention to the stability, throughput, and other common indicators of the equipment, but these do not represent the true "strength" of the Broadband Router ". "Everything has its own principles." The same is true for the features of a Broadband Router. Why do manufacturers bother designing these functions? In fact, these functions are not a weakness. On the contrary, they are very practical. We will introduce them to you below.

DMZ host and Virtual Server

I was able to count as a BT downloading madman in college, and there are certainly not a few users who have such "hobbies. In fact, everyone is just downloading it. We do not know that the DMZ and virtual servers in the Broadband Router can help us download BT more frantically.

The full name of DMZ is Demilitarized Zone. The Chinese name is "isolation Zone", also known as "non-military Zone ". It is a buffer zone between a non-security system and a security system to solve the problem that external networks cannot access internal network servers protected by firewalls, this buffer zone is located in a small network area between the enterprise's internal network and the external network. Some public server facilities can be placed in this small network area, such as Enterprise Web servers, FTP servers, and forums. Using this DMZ area is equivalent to adding a level to the firewall to effectively protect the internal network.

The virtual server can perform destination address translation to map the IP address and port number of the WAN port to the IP address of the server in the LAN. All service ports (such as FTP service ports) of the WAN Port) will be redirected to the corresponding internal port of the server in the specified LAN. That is, you can set up virtual servers to access internal servers from the Internet and enjoy services such as Web, E-mail, and FTP.

In fact, the DMZ host is actually a default virtual server. If the device receives a connection request from an external network, it first looks for the virtual service list. If there is a matched project, send the request message to the corresponding virtual server. If no matching item is found, it is forwarded to the DMZ host. In an environment where multiple people share a Broadband Router and access the Internet, if a user frequently downloads BT and wants to speed up, he can enable DMZ or create a dedicated BT virtual server.

How to enable DMZ in a Broadband Router and create a virtual server

To enable DMZ, go to the settings page, expand "advanced", select "Internet", and select "enable" in "DMZ type" in the right column ", in the "PC" column, select the DMZ host (for example, a computer that wants to accelerate BT) and click "save ". To create a virtual server, select "virtual server" under "advanced", and select the service type to be applied in the "server" column. If there is no type you want to enable, you can select "enable" in the "Features" column, enter a name, select the host in the LAN, set the port, and click "Add new server.
