  • sudo ufw allow 1194/udp

  • Consider enabling certificate-based authentication for enhanced ⁢security. This involves creating CA⁣ (Certificate Authority) and⁢ client certificates. Start by​ creating the necessary directories:
  • mkdir ~/openvpn-ca && cd ~/openvpn-ca
    mkdir certs crl newcerts private
    chmod 700 private

  • Next, generate the⁤ CA ​certificate ⁤and key:
  • openssl req -new -x509 -extensions v3_ca -keyout private/ca.key -out certs/ca.crt -days 3650

  • Finally, ​generate client⁢ certificates using the following command:
  • openssl req -new -nodes -keyout private/client.key -out certs/client.csr -days 3650

By following these ⁤tips and best practices, you can effectively configure and customize OpenVPN on your ⁢Ubuntu 20.04 server, ensuring a secure and⁤ efficient VPN‌ solution.
