The sky is the limit: How to set up a LAN from a different computer

As we know, computers and cell phones in the same office or home can easily form a local area network to access each other’s resources. However, for computers and other devices in different regions, there is no way to set up LAN directly due to public IP and port restrictions. With the help of “Dandelion” software, computers scattered in different places can realize the function of LAN by VPN, and share documents, pictures and videos in different computers, cell phones and servers conveniently.

Trivia: What is VPN?

VPN is short for Virtual Private Network, which is a remote access technology and simply means using software to set up a private network on a public network. In this way, as long as the computer or cell phone with the software installed is networked, it can form a virtual private network, and the devices can visit each other through virtual IP addresses to achieve a LAN-like effect.

First of all, go to下载适合自己设备的客户端. Here take Windows platform as an example, after launching the client, first go to the website for registration, and then log in at the client after the registration is completed. After successful login, the virtual NIC will be loaded automatically and you can see your computer VPN address, similar to the form of (Figure 1).

In order to check the network status, you can double-click one of the devices directly, and the command prompt Ping will pop up automatically to check the access network status by this command (Figure 2).


Figure 2 Ping command

“Dandelion” supports multiple devices and systems, so if you install the Dandelion client on these devices, they can access each other. For example, a group has two branches in A and B. Now, employee A of company A needs to share the information on computer B of company B. First, install the Dandelion client on computer A and B and log in each. Then set the shared folder on B’s computer, assuming it is d:cfan, and B needs to copy the information on his computer to d:cfan, right-click the directory and select “Share”, click “Share”, and follow the prompts to set the directory as shared (Figure 3). Click “Share” and set the directory as shared (Figure 3).


Figure 3: Setting up sharing

Suppose A’s computer is connected to the Internet, open “Computer→Network”, then enter “\” in the address bar, where the IP address is the virtual address assigned to A by Dandelion (the IP address displayed in the client). After you enter, you can see the shared directory in the Explorer window that opens, just copy and paste the shared information (Figure 4).

With the Dandelion client, computer A and B are in the same LAN, so we can use the “Network” component to access each other, or use the system’s own remote desktop to connect and easily control the remote computer. Of course, it is not limited to inter-computer access, with the help of Dandelion we can also achieve cell phone, computer, tablet inter-access. For example, if you are on the go, you need to access your computer’s files via your cell phone.

As above, first install Dandelion on different devices and log in, and share the same operation on the computer side. Click “Connect” after starting Dandelion on your phone, and then you will be prompted to create a VPN connection, click “Yes” to connect, and then the IP address and device information of the current device will be displayed after successful connection (Figure 5).

Install the free remote control software Remote Desktop provided by Microsoft on your cell phone, launch the application and click “+” to add the IP (i.e. VPN address) of the host you need to connect to remotely and the account name of the host (Figure 6).

Tip: In order to facilitate other users’ access, we can set it to start in Dandelion settings and configure it as a system service. Later, as long as the computer is open, we can remote control the computer from anywhere on the phone or tablet.
