Load Balancing Mikrotik + Proxy

Load balancing Mikrotik kali ini saya coba dengan 2 line speedy digabungkan dengan mesin squid web proxy, berbeda dengan load balancing versi sebelum ini. Pada load balancing kali ini saya tambahkan redirect ke squid dengan mengunakan mikrotik sebagai mesin load balancer-nya.

Langkah pertama install dulu mikrotik seperti di tutorial ini, lalu sebelum mencoba, saya sarankan mereset mikrotik dulu, supaya kembali pada settingan default. untuk reset bisa menggunkan perintah : “/sy reset“.

Setelah Mikrotik diinstall, pastikan dulu bahwa interface pada mikrotik ada 4biji, interface 1 menuju ke klient, interface 2 menuju ke Speedy 1, interface 3 menuju ke speedy 2 dan interface 4 menuju ke squid web proxy.

untuk setting squid bisa dilihat disini, dan baiklah kita mulai copy paste setting dibawah ini pada terminal Mikrotik :

/in ethset ether1 name="intranet"  disabled=no
set ether2 name="speedy-1"  disabled=no
set ether3 name="speedy-2"  disabled=no
set ether4 name="proxy"  disabled=no

Ohya mikrotik yang saya gunakan untuk testing kali ini adalah versi bajakan 2.9.27, untuk versi 3 keatas silahkan lihat setting mangle-nya pada tulisan ini dan tulisan ini. ohya kalo pake bajakan saya sarankan setelah settingannya berjalan, silahkan beli Mikrotik ASLI ya!!
