experience

Setting up OpenVPN:

  • brilliant tutorial (RU)
    login-password auth (RU) (even if client certificate is not required, client’s config must contain server’s ca certificate)

    Creating certificate for new user:

    cd ~/openvpn-ca
source vars
./build-key client1

cd ~/client-configs
./make_config.sh client1

    Do not forget about:

    • better use 443 tcp port
      however udp is much more stable (though use 443 udp)
    • firewall: sudo ufw allow 443/tcp
    • enable ipv4_forwarding
    • ccd and routes in server vpn config to enable access to internal infrastructure

    Handy commands:

    • look connected users: cat /etc/openvpn/openvpn-status.log
    • start vpn service: sudo systemctl start openvpn@server
    • checking log: sudo journalctl -xe
    • check available ciphers and digests: openvpn --show-ciphers --show-digests
    • restart firewall: sudo ufw disable && sudo ufw enable
