Topology
CLIENT 1 ------- HOST A ---------------- HOST B --------- CLIENT 2
ovpn server ovpn client
2345::1/64
Host A akan berfungsi sebagai OpenVPN Server.
OS : Ubuntu 18.04 IP : 192.168.0.239/24 (IP public) hostname : vpnserver
Host B akan berfungsi sebagai OpenVPN client
OS : Ubuntu 18.04
Konfigurasi OpenVPN Client
Pastikan openvpn terinstalsi
sudo su apt install openssh-server openvpn
Edit /etc/hosts isi dengan nama OpenVPN server
192.168.0.239 vpnserver
Jalankan OpenVPN client
cd ~ sudo su openvpn --config client.ovpn
Akan keluar kira-kira

Cek interface, akan muncul tun0 yang ada IPv6-nya
ifconfig

Cek sambungan
ping -c3 10.8.0.1
Sample output:

Cek routing
route -n
Sample output
