Topology
CLIENT 1 ------- HOST A ---------------- HOST B
ovpn server ovpn client
HOST C
ovpn client
Host A akan berfungsi sebagai OpenVPN Server.
OS : Ubuntu 18.04 IP : 192.168.0.239/24 hostname : vpnserver
Host B akan berfungsi sebagai OpenVPN client
OS : Ubuntu 18.04
Host C akan berfungsi sebagai OpenVPN client
OS : Ubuntu 18.04
Buat Client Config di Server
Konfigurasi client dibuat di server menggunakan
cd /usr/local/src/ bash openvpn-install.sh
Keluar
Looks like OpenVPN is already installed. What do you want to do? 1) Add a new user 2) Revoke an existing user 3) Remove OpenVPN 4) Exit Select an option [1-4]:
Pilih 1 dan akan dibuatkan config untuk client2 dst. File ini ada di /root/client2.ovpn.
Copykan file tersebut ke client.
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 client2.ovpn
Akan keluar kira-kira

Cek interface, akan muncul tun0
ifconfig

Cek sambungan
ping -c3 10.8.0.1
Sample output:

Cek routing
route -n
Sample output

Anda sudah tersambung ke VPN dengan IP 10.8.0.0/24
