Several ways of Intranet penetration

How to access apps on your laptop at home from anywhere ？ How to make the LAN server can be accessed anywhere ？ There are many similar needs , We can use one solution ： Intranet through . There are many tools and methods for intranet penetration , Such as Ngrok、Ssh、autossh、Natapp、Frp、Lanproxy、Spike、 Peanut shell wait , Today I will introduce to you an intranet penetration tool that Xiaobian personally tested —— Quick analysis of Beijing jinwanwei , And gives a tutorial , For your study and reference .

After setting up the server , utilize Fast parsing Do port mapping , Bind the domain name to provide Internet access . You can bind your own domain name , You can also directly use the free custom secondary domain name . As long as there is local networking , Access to the Internet , That is, it can be done through Fast parsing Port mapping settings , Connect the local server to the intranet IP The port is mapped to its own domain name or automatically generated free custom secondary domain name , Provide Internet access through domain name . The following is the detailed implementation process ：

（1） Define intranet access . First, make sure that you can normally access your target application in the LAN , Specify the intranet used IP And Intranet port number .

（2） Add intranet mapping . On the intranet server , Or on another host in the LAN , Install and log in to quick resolve add port mapping . Here, you can directly set the application's intranet address to the Internet address in one step .

（3） The information related to mapping and filling in are ：

Application port （ Common server ports ）：WEB The server （ Web server ）：80 port ;FTP The server （ File server ）：21 port ; Terminal Server ：3389 port ; Mail server ：25 port （SMTP） and 110 port （POP）;VPN The server ：1723 port .

Public port type ： Choose according to your own application needs .

Intranet address ： Intranet access to fixed address . It can be a fixed intranet IP Or computer name . If the mapping is used locally on the server , It is recommended to fill in 127.0.0.1 Format .

（4） Achieve Internet domain name access . After the domain name resolution takes effect, the intranet mapping takes effect quickly , That is, you can surf the Internet in any environment , Access through domain name and Internet port . Generally, the new domain name record takes effect quickly ; After modifying the domain name record , Need to wait for a while DNS Take effect after automatic refresh .
      Intranet through , Intranet mapping , It is to map the internal network port to the external network . The principle is , Connect the domain name to the local intranet IP host , adopt Quickly resolve software binding relationships . When accessing the mapped domain name on the Internet , The fast parsing service will identify the corresponding , And point to the corresponding client to analyze and realize data exchange .

Achieve intranet penetration , Home 、 Employees and branches on business trips , You can remotely access the corresponding services of the enterprise intranet at any time , Visit the company OA、CRM、ERP System Do telecommuting . Fast parsing Intranet penetration can also help users Set up a website in the office or at home 、FTP、Mail Wait for the server ; utilize ADSL Wait for broadband connection to set up video surveillance 、 Video conference system ; utilize ADSL And so on VPN Access And so on .
