Hari ini saya ingin menulis dokumentasi saya belajar tentang mikrotik, terutama dalam hal loadbalancing.. okelah langsung saja..

Kita buat dulu address-list nya

/ip firewall address-list
add address=192.168.3.0/24 list=local
add address=192.168.4.0/24 list=local
add address=192.168.9.0/24 list=local
add address=192.168.99.0/24 list=local
add address=172.16.1.0/30 list=local
add address=192.168.7.0/29 list=local
add address=192.168.8.0/30 list=local
add address=192.168.11.0/29 list=local
add address=123.123.123.0/24 list=local
add address=192.168.18.0/30 list=local
add address=192.168.10.0/24 list=local
add address=192.168.88.0/24 list=local

Selanjutnya kita buat mangle nya

/ip firewall mangle
add action=mark-connection chain=prerouting comment="Loadbalance PCC" \
    dst-address-list=!local dst-address-type=!local new-connection-mark=\
    WAN1_conn per-connection-classifier=both-addresses-and-ports:2/0 \
    src-address-list=local
add action=mark-connection chain=prerouting dst-address-list=!local \
    dst-address-type=!local new-connection-mark=WAN2_conn \
    per-connection-classifier=both-addresses-and-ports:2/1 src-address-list=\
    local
add action=mark-routing chain=prerouting connection-mark=WAN1_conn \
    new-routing-mark=to_WAN1 src-address-list=local
add action=mark-routing chain=prerouting connection-mark=WAN2_conn \
    new-routing-mark=to_WAN2 src-address-list=local

Terakhir kita buat route nya.

ip route
add check-gateway=ping distance=1 gateway=pppoe-indihome-1 routing-mark=to_WAN1
add check-gateway=ping distance=1 gateway=pppoe-indihome-2 routing-mark=to_WAN2
add check-gateway=ping distance=1 gateway=pppoe-indihome-2
add check-gateway=ping distance=2 gateway=pppoe-indihome-1

Sudah selesai, jadi kalo misalkan nambah WAN (ISP) yah tinggal lanjutin aja tu mangle nya..

Semoga bermanfaat
