http://ngrok.com merupakan servis yang memungkinkan kita mengakses private server dari luar, meskipun tidak memiliki public IP adress.

Buat akun di ngrok.com, install agent ngrok di server, kemudian jalankan agent tersebut.

Alamat web public yang di-generate akan berubah-ubah setiap kali agen restart. Tentu ini karena kita menggunakan free account :)
