Step 3: Download the configuration file to your device

With step 2, you can use and connect. However, I will write this extra step to help you download the configuration file directly from the browser to the client computers. Please run the following command to execute

cd /root && python3 -m http.server
Serving HTTP on port 8000 ( ...

Then you access the browser, enter server-ip:8000 to view the configuration file and download it. If you can’t access the port 8000, the port is probably not open on the firewall system. Please refer to the following article to open

Step 4: Set up using OpenVPN

To use VPN on your computer or phone, you must make VPN Client settings to connect. Some software for each operating system such as:

1. Set up using OpenVPN on your computer

1.1 Configuring OpenVPN on Windows

After installing the OpenVPN app on Windows and downloading the file *.opvn, Open the newly installed OpenVPN App. Then you select FILE and select BROWSE and select file.opvn and click connect

1.2 Configuring OpenVPN on MacOS

With the configuration on MacOS, I use an App called OpenVPN to set up a VPN.

Then you select FILE and select BROWSE and select file.opvn

Then you choose CONNECT to connect. If asked for a password, enter the password you created in the first step

2. Set up using OpenVPN on mobile

OpenVPN also supports mobile devices. To download, please visit the corresponding link below.

Please download the .opvn file to your mobile device. Then open this file with the installed OpenVPN application

Then you choose ADD to add the file.

Next you choose Connect after import (Connect after import) => ADD

Similar to VPN connection on MAC OS.

Step 5: Check Internet connection

After the connection is complete. Now I will access the Internet to check if it works or not. And I check if the IP is correct or not.
