To connect from the external network to the servers in the LAN of the servers in the network, we need to configure the VPN Server for access, in this article, I will use Open VPN Server
Concept
- OpenVPN is a full-featured SSL VPN (Virtual Private Network). It implements Layer 2 or 3 network extensions with the SSL/TLS protocol. It is open-source software and is distributed under the GNU GPL. VPN allows you to securely connect to an insecure public network such as WiFi at airports or hotels. VPN is also required to access your company, business, or home server resources. You can bypass geographically blocked websites and increase online privacy or security. This guide provides step-by-step instructions to configure an OpenVPN server on an Ubuntu Linux 22.04 server.
Instructions
To perform the installation, follow these steps:
Step 1: Update your system, your operating system, here I use Ubuntu 22.04
We update the packages with the apt command
sudo apt update && sudo apt upgrade -y
Step 2: Find and record your IP
To find your IP, we use the command:
ip a
ip a show enp4s0
Step 3: Download and run the ubuntu-22.04-lts-vpn-server.sh script
wget https://raw.githubusercontent.com/Nyr/openvpn-install/master/openvpn-install.sh -O ubuntu-22.04-lts-vpn-server.sh
then we set permissions for the newly downloaded file with the command
chmod -v +x ubuntu-22.04-lts-vpn-server.sh
Run ubuntu-22.04-lts-vpn-server.sh to install OpenVPN Server
sudo ./ubuntu-22.04-lts-vpn-server.sh
then we check the status of openVPN
sudo systemctl status openvpn-server@server
Then we download the client.ovpn file to the machine that needs to go into VPN
We find the .ovpn file with the command
sudo find / -iname "*.ovpn" -ls
So we have successfully installed OpenVPN
Next, we install the Open VPN Client for the machine that needs to go into VPN
Here I use Mac M1 and successfully connect
