Simple Analysis of practical applications of broadband Routers

At present, broadband routers are widely used and the market demand is constantly increasing. So I have studied some small skills in the practical application of broadband routers, I would like to share it with you here and hope it will be useful to you. Many people want to create their own websites. At the very beginning, they wanted to watch the relevant tutorials on the Internet when reading the materials in the library. But when it comes to jamming, I don't know what to do. Many people want to create a dynamic domain name, which makes it difficult for many people to set up their own broadband routers. Don't know? Next let's look at it.

The Dynamic Domain Name Service is short for DDNS, that is, Dynamic Domain Name Service. For users who use ADSL Broadband Internet access, a new IP address is assigned for each dial-up. When the DDNS service is enabled, the resolution service between a fixed domain name and a dynamic IP address can be automatically implemented. For example, if the IP address of a Google website is 64.233.189.104, this domain name is easy to remember. When we access the Internet through ADSL, the IP addresses assigned each time are different, therefore, static IP addresses cannot be resolved directly, but dynamic IP addresses can be resolved to fixed domain names through some dynamic Domain Name Service websites. In this way, others can also enjoy the services (such as websites and FTP) provided by your computer through a fixed domain name ).

How to enable the DDNS dynamic Domain Name Service of a Broadband Router

First, enter the IP address of the Broadband Router in the browser to enter the configuration menu, select "dynamic domain name" in "advanced", and then select your own registered service provider in the DDNS service on the right bar, for example, "Cn99" (if you have not registered with this website, you can click the "website" button after this option to open the website, click "New User Registration" on the homepage to register the domain name. Then, enter the registered user name, password, and domain name in the "DDNS data" column, and click "save ". After the website service is configured, others can access your website through this domain name.

VPNPass-through

In order to obtain the latest company data in a timely manner, many companies in other regions need to use the Internet to access the internal servers of the headquarters to obtain data, in this case, the "VPNPass-through" function in the Broadband Router is needed. To learn about VPNPass-through, you must first know what Virtual Private Network is. It does not have a dedicated Network physical connection, but uses a public Network (such as the Internet) to establish a temporary, secure, and simulated point-to-point connection, we can also call it a "network in the network" (a bit of a TV picture ).

Many organizations or individuals use Broadband Router sharing, to establish a VPN, the Broadband Router needs to have the VPNPass-through function (the function of passing VPN data packets is called VPNPass-through). This function supports configuring the VPN of the client and receiving feedback packets, with the support of this function, other computers in the network can establish virtual connections with external VPN servers. There is also a VPNServer Broadband Router (which supports dial-in) on the market. It not only supports the VPNPassthrough function (that is, the workstation working below can smoothly establish a connection with the VPNServer ), in addition, it is a VPNServer with all VPNServer functions.

How the client establishes a virtual connection

To establish a virtual connection with an existing VPNServer at the headquarters of the company, you must first enable the VPN function of the Broadband Router. I will take the CIDR wide IP806SM Broadband Router as an example. Log on to the Management page of the Broadband Router. Find "security" in "Administrator" and select "allow VPN to pass" in the right column ".

Then, set it on the client for virtual connection. In Windows XP, you can set the parameters as follows: "Control Panel> network connection", and click "Create a new connection ", then, select "network connected to my workplace" and "virtual network dedicated connection", and enter the name and Host IP address (including domain name) as prompted ), click "finish". In the displayed window, enter the account and password provided by the VPN Server, and click "Connect. If the connection is established for the first time, the system requires the user to enter the phone number of the region. This prompt is not displayed if other connections (such as connections connected to the Internet through ADSL) have been established before the VPN connection is established. After the connection, you can access the shared resources by entering the server name or server address in the address bar of the browser.
