<p>Berawal dari setup koneksi VPN untuk berinternet ria dari laptop saya, ternyata hal tersebut menyebabkan saya tidak bisa terkoneksi ke beberapa perangkat yang hanya berbeda 1 hop network saja. Setelah ditelusuri, hal tersebut dikarenakan ketika melakukan koneksi VPN, otomatis akan membuat gateway tersendiri yang menyebabkan traffic keluar harus melewati gateway VPN tersebut.</p>
<p>Untuk mengatasi hal tersebut, kebetulan saya menemukan cara mudahnya, yaitu dengan menambahkan routing static pada Mac Os</p>
<pre>Contoh : 
IP Address saya : 192.168.60.123/24 
Gateway default : 192.168.60.1 
IP Address VPN : 10.8.0.19 
Gateway VPN : 10.8.0.1</pre>
<p>Case saya, ingin bisa terkoneksi ke jaringan 192.168.80.0/24 dimana kalau tanpa VPN, menggunakan default gateway 192.168.60.1 bisa langsung terkoneksi ke jaringan 192.168.80.0/24, tetapi kalau pakai VPN, otomatis semua koneksi akan melewati gateway VPN 10.8.0.1 dimana gateway ini tidak bisa terkoneksi ke jaringan 192.168.80.0/24, berikut langkah-langkah eskalasinya</p>

<p>1. Buka Terminal, lalu jalankan command berikut, nanti akan diminta memasukkan password administrator</p>
<pre>sudo route -n add -net 192.168.80.0/24 192.168.60.1</pre>
<p>Arti dari command diatas yaitu menambahkan routing static agar traffic menuju jaringan 192.168.80.0/24 diarahkan melewati gateway 192.168.60.1</p>
<p>2. Pastikan network tersebut sudah masuk ke dalam table routing Mac OS dengan menjalankan command <strong>netstat -rn</strong></p>
<pre>rizky@Rizkys-MacBook-Air % netstat -rn

<span style="color: #0000ff;">192.168.80 192.168.60.1 UGSc en0 
</span></pre>
<p>Jika sudah ada, silakan dicoba kembali untuk koneksi ke jaringan 192.168.80.0/24 dengan menggunakan VPN, semestinya sudah bisa</p>
<p>Mungkin cukup sekian, semoga bermanfaat</p>
