<p>Assalamualaikum Wr. Wb</p>
<p>Berawal ketika saya mendaftar layanan google cloud, saya mendapat credit sebesar $300 selama setahun, disini saya gunakan untuk membuat 1 buat VM Instance pada google cloud, VM tersebut saya install untuk anti spam email, setelah system up dan berjalan, saya testing port 25 dari internet, tapi kok tidak bisa yaa, saya coba baca-baca referensi ternyata secara default google cloud hanya open port 80, 443 serta 22 dari luar, untuk port sisanya ditutup/di block</p>

</blockquote>
<p>Untuk contoh dibawah ini kita akan coba open port 25 dari internet</p>
<p>Berikut langkah-langkah nya</p>
<h3><span style="color: #00ccff;">Login ke akun Google Cloud</span></h3>
<p>Klik pada bagian Product &#038; Services (bagian garis 3), kemudian scroll kebawah dan cari menu VPC Network | Firewall rules</p>

<p>Kemudian akan muncul form untuk konfigurasi port apa yang akan diopen dari luar</p>

<pre>Targets : Pilih All instance in the network 
 
Source filter : pilih IP ranges 
 
Source IP ranges : Isi dengan 0.0.0.0/0 karena incoming berasal dari internet, yang artinya semua IP akan di dnat nantinya 
 
Second source filter : pilih none saja 
 
Protocols and ports : Pilih Specified protocols and ports karena hanya akan membuka port 25 saja 
 
Kemudian isikan dengan format tcp:25 
 
Note : jika ada beberapa port, bisa dipisah dengan tanda semicolon ;</pre>
<p>Kemudian klik create</p>
<p>Berikut hasil rule yang baru dibuat tadi</p>
