Ubuntu 18.04 LTS Set Up OpenVPN Server
To set up an OpenVPN server on Ubuntu 18.04 LTS, you can follow these steps:
- Install the OpenVPN package by running the command:
sudo apt-get install openvpn - Create a directory for the server configuration files:
sudo mkdir /etc/openvpn/server - Copy the sample server configuration file to the server directory:
sudo cp /usr/share/doc/openvpn/examples/sample-config-files/server.conf.gz /etc/openvpn/server/ - Unzip the server configuration file:
sudo gzip -d /etc/openvpn/server/server.conf.gz - Edit the server configuration file to suit your needs. For example, you can specify the IP address of the server, the port to listen on, and the encryption settings.
- Create a directory for the client configuration files:
sudo mkdir /etc/openvpn/client - Copy the sample client configuration file to the client directory:
sudo cp /usr/share/doc/openvpn/examples/sample-config-files/client.conf /etc/openvpn/client/ - Edit the client configuration file to match the server settings, such as the server IP address and port.
- Generate the server's private key and certificate by running the command:
sudo openvpn --genkey --secret /etc/openvpn/server/ta.key - Start the OpenVPN server by running the command:
sudo systemctl start openvpn@server - Check the status of the server by running the command:
sudo systemctl status openvpn@server - Configure the firewall to allow traffic to the OpenVPN port, and also configure the client to connect to the server.
