1/2

Pagi tadi mencoba untuk setting Load Balancing dengan Menggunakan Mikrotik, adapun gambaran

simpel network nya adalah sebagai berikut :

Ether1 berhubungan dengan ISP1 (WLAN), Ether2 berhubungan dengan Speedy dan Ether3 untuk

jaringan localnya..

Dengan menggunakan mikrotik ada 3 komponen utama yg digunakan untuk membuat Loadbalancing yaitu :

ip firewall nat

ip firewall mangle

ip route

Berikut lampiran konfigurasinya :

[admin@Mikrotik] > ip address print

Flags: X - disabled, I - invalid, D - dynamic

Untuk membuat supaya ip gateway lokal bisa dijadikan DNS lokal maka pengaturannya ada

dibawah ini, dan yg perlu diperhatikan adalah yang ada tulisan allow-remote-request : yes
