How to use shared folders on different local area networks?

LAN shared folder is a method of implementing file sharing within a LAN, It allows users within the local area network to access and edit folders of other users. This method can improve work efficiency, Facilitate collaboration among team members. This article will provide a detailed introduction on how to share folders between different local area networks.

1. What is a local area network?

LAN (Local Area Network, abbreviation LAN) It refers to a relatively small geographical area (Like a family, Office or school) A network composed of computers and other devices connected by wired or wireless means. Devices within the local area network can communicate and share resources through network protocols.

2. Why is it necessary to share folders between different local area networks?

In practical work, We often need to collaborate with other departments or teams, At this point, it is necessary to share folders between different local area networks. By sharing folders, We can easily transfer files, Collaborative document editing, Shared resources, etc, improve work efficiency.

3. How to share folders between different LANs?

To be inSharing folders between different local area networks, We need to use some network technology, as VPN (Virtual Private Network, Virtual Private Network) , SMB (Server Message Block, Server message block) Agreements, etc. Below, we will introduce these two methods separately.

3. 1 use VPN

VPN It is a technology for establishing a virtual private network on a public network, It can simulate a private network environment on a public network, Enable users within different local area networks to communicate and share resources as if they were within the same local area network. To share folders between different local area networks, We can build one VPN The server, Enable users from different local area networks to connect to this VPN On the server, Thus achieving folder sharing.

build VPN There are many methods for servers, Here Windows System as an example, Introduce how to build a simple VPN The server:

step 1: open "control panel" " "Network and Internet" " "Network and Sharing Center" , Click on the left side "Change adapter settings " .

step 2: Find your local connection (Usually displayed as "Ethernet" or "Wireless network connection" ) , Right click, choice "attribute" .

step 3: In the pop-up property window, double-click "Internet Protocol version 4 (TCP/IPv4) " .

step 4: In the pop-up IPv4 In the attribute window, Check the box "Use the following IP address" , Then enter a static input IP address, Subnet mask and default gateway. These pieces of information can be found in VPN Found within the local area network where the server is located.

step 5: click "determine" Save Settings. next, We need to configure VPN The server. open "control panel" " "program" " "Enable or disable Windows function" , Check the box "Internet Protocol version 6 (TCP/IPv6) " , Then click "determine" .

step 6: open "control panel" " "management tool" " "Routing and Remote Access" , Right click "Router" , choice "Configure and enable routing and remote access" .

step 7: In the pop-up window, choice "Custom configuration" , Then click "next step" .

step 8: choice "VPN visit" , Then click "next step" .

step 9: choice "VPN Router" , Then click "next step" .

step 10: Enter a pre shared key, This is the connection VPN The password that needs to be entered. Then click "next step" .

step 11: complete VPN Server configuration. Now, Other users within the local area network can connect to this VPN On the server, Implement folder sharing.

3. 2 use SMB agreement

SMB Protocol is a network protocol used for sharing files and printers within a local area network. To share folders between different local area networks, We can use support SMB Protocol file transfer tool, as FileZilla, WinSCP etc. These tools can help us transfer files between different local area networks, Implement folder sharing.

with FileZilla take as an example, Introduce how to use SMB Protocol for sharing folders between different local area networks:

step 1: Download and install FileZilla Client software.

step 2: open FileZilla Client software, input SMB The server's IP address, Username and password. These pieces of information can be found in SMB Found within the local area network where the server is located.

step 3: click "Quick Connect" Button, connection to SMB The server. After successful connection, We can see that SMB Files and folders on the server.

step 4: To be in SMB Create a new folder on the server, You can right-click on the blank space, choice "New Folder" , Then enter the folder name. The newly created folder will appear in SMB On the server.

step 5: To start from SMB Download files from the server to the local computer, You can right-click on the file, choice "Downloads" . After downloading is complete, The file will appear on the local computer.

step 6: To upload files from the local computer to SMB The server, You can right-click on the file, choice "upload" . After uploading is completed, The file will appear in SMB On the server.

Through the above methods, We can achieve folder sharing between different local area networks. It should be noted that, To ensure network security, We should set a strong password, Regularly update passwords, Measures such as restricting access permissions. meanwhile, We can also use a firewall, Antivirus software and other tools are used to protect the security of the network.
