Topology
CLIENT 1 ------- HOST A ---------------- HOST B
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

Perhatikan di bagian agak bawah terlihat ada beberapa setup IPv6. Selanjutnya cek Interface, akan muncul tun0 yang ada IPv6-nya
ifconfig
tun0: flags=4305<UP,POINTOPOINT,RUNNING,NOARP,MULTICAST> mtu 1500
inet 10.8.0.2 netmask 255.255.255.0 destination 10.8.0.2

RX errors 0 dropped 0 overruns 0 frame 0
TX packets 3898 bytes 324037 (324.0 KB)
TX errors 0 dropped 106 overruns 0 carrier 0 collisions 0
Perhatikan IPv4 address keluarga 10.8.0.0/16 dan ada IPv6 address sesuai dengan settingan yang ada di OpenVPN Server. Selanjutnya cek sambungan menggunakan IPv6,
ping -I tun0 2345::1
Sample output:
PING 2345::1(2345::1) from 2345::1000 tun0: 56 data bytes 64 bytes from 2345::1: icmp_seq=1 ttl=64 time=0.610 ms 64 bytes from 2345::1: icmp_seq=2 ttl=64 time=0.692 ms 64 bytes from 2345::1: icmp_seq=3 ttl=64 time=0.582 ms 64 bytes from 2345::1: icmp_seq=4 ttl=64 time=0.603 ms 64 bytes from 2345::1: icmp_seq=5 ttl=64 time=0.625 ms 64 bytes from 2345::1: icmp_seq=6 ttl=64 time=0.625 ms ^C --- 2345::1 ping statistics --- 6 packets transmitted, 6 received, 0% packet loss, time 5110ms rtt min/avg/max/mdev = 0.582/0.622/0.692/0.046 ms
Cek routing
ip -6 route show
Pastikan ada routing ke IPv6 address
