Several VPN protocols are available; however, OpenVPN is among the most trusted and widely adopted solutions suitable for business needs due to its security and flexibility.

Step 1: Installing OpenVPN on Linux

sudo apt update sudo apt install openvpn easy-rsa -y

Step 2: Setting Up Easy-RSA for Public Key Infrastructure (PKI)

  1. Create the Easy-RSA directory and initialize the PKI: make-cadir ~/easy-rsa cd ~/easy-rsa ./easyrsa init-pki
  2. Build the CA (Certificate Authority): ./easyrsa build-ca
  3. Create server and client certificates: ./easyrsa build-server-full server nopass ./easyrsa build-client-full client1 nopass

Step 3: Configuring the OpenVPN Server

- Copy sample server configuration: gunzip -c /usr/share/doc/openvpn/examples/sample-config-files/server.conf.gz | sudo tee /etc/openvpn/server.conf - Modify the configuration file to specify correct paths and security parameters, activate necessary features such as cipher, auth, and compress ontarget your needs.

Step 4: Enabling IP Forwarding and Firewall Rules

- Enable IP forwarding: sudo sysctl -w net.ipv4.ip_forward=1 sudo tee -a /etc/sysctl.conf
