Cara Setting Load Balance Mikrotik ( 3 Modem di gabungkan dalam satu Mikrotik Router)

Jika anda mempunyai 3 buah modem kemudian anda ingin gabungkan menjadi satu dengan mikrotik router, berikut ini cara settingnya:

• Remote Mikrotik Router anda dengan Winbox,download winbox ((DI SINI))
• Di halaman utama winbox pilih “New Terminal” kemudian beri nama interface ether0,ether1,ether2,ether3 dengan perintah:

/interface print

/interface set 0 name=modem1;/interface set 1 \

name=modem2;/interface set 2 name=modem3;/interface set 3 name=local

Seperti gambar di bawah ini:

• Masukkan ip address untuk modem1,modem2,modem3,dal local (untuk local ip addressnya ciptaan sendiri),dengan perintah:

/ip address add address=192.168.11.2 \

netmask=255.255.255.0 interface=modem1

/ip address add address=192.168.12.2 netmask=255.255.255.0 \

interface=modem2

/ip address add address=192.168.13.2 \

netmask=255.255.255.0 interface=modem3

/ip address add address=192.168.99.1 \

netmask=255.255.255.0 interface=local

Seperti gambar di bawah ini:

• Kemudian masukkan gateway untuk modem1,modem2,modem3 dengan perintah:

/ip route add dst-address=0.0.0.0/0 \

gateway=192.168.11.1 distance=1 \

check-gateway=ping

/ip route add dst-address=0.0.0.0/0 \

gateway=192.168.12.1 \

distance=1 check-gateway=ping

/ip route add dst-address=0.0.0.0/0 \

gateway=192.168.13.1 distance=1 \

check-gateway=ping

Seperti gambar di bawah ini:

• Kemudian masukkan DNS,dengan perintah:

/ip dns set servers=203.130.193.74,203.130.208.18 \

allow-remote-request=yes

Jika timbul keterangan bad argument name servers (line 1 column 13) maka ubah perintahnya seperti di bawah ini:

/ip dns set primary-dns=203.130.193.74

/ip dns set secondary-dns=203.130.208.18 \

allow-remote-request=yes

Seperti gambar di bawah ini:

• Kemudian masukkan NAT untuk modem1,modem2,modem3,dengan perintah:

/ip firewall nat add chain=srcnat out-interface=modem1 \

action=masquerade

/ip firewall nat add chain=srcnat out-interface=modem2 \

action=masquerade

/ip firewall nat add chain=srcnat out-interface=modem3 \

action=masquerade

Seperti gambar di bawah ini:

• Kemudian Address-list,dengan perintah:

/ip firewall address-list add \

address=192.168.11.0/24 list=lokal

/ip firewall address-list add address=192.168.12.0/24 \

list=lokal;/ip firewall address-list \

add address=192.168.13.0/24 list=lokal

/ip firewall address-list add address=192.168.99.0/24 \

list=lokal

Seperti gambar di bawah ini:

• Kemudian Mangle Traffic lokal,dengan perintah:

/ip firewall mangle add action=accept \

chain=prerouting dst-address-list=lokal \

in-interface=local comment=”traffic_local”

/ip firewall mangle add \

action=accept chain=output \

dst-address-list=lokal

Seperti gambar di bawah ini:

• Kemudian Buat Mangle untuk Mark-Connection Traffic ,Dengan perintah:

/ip firewall mangle add action=mark-connection \

chain=prerouting connection-mark=no-mark in-interface=modem1 \

new-connection-mark=con-from-modem1 \

passthrough=yes comment=”Traffic_modem1”

/ip firewall mangle add action=mark-connection \

chain=prerouting connection-mark=no-mark in-interface=modem2 \

new-connection-mark=con-from-modem2 \

passthrough=yes comment=”Traffic_modem2”

/ip firewall mangle add action=mark-connection \

chain=prerouting connection-mark=no-mark in-interface=modem3 \

new-connection-mark=con-from-modem3 \

passthrough=yes comment=”Traffic_modem3”

Seperti gambar di bawah ini:

• Kemudian buat Mangle supaya traffic DNS melewati Gateway ISP modem1,modem2,modem3 ….bukan dari gateway yang lain….perintahnya:

/ip firewall mangle add action=mark-connection chain=output comment=dns \

dst-address=203.130.193.74 dst-port=53 new-connection-mark=dns passthrough=yes \

protocol=tcp

/ip firewall mangle add action=mark-connection chain=output \

dst-address=203.130.193.74 dst-port=53 new-connection-mark=dns passthrough=yes \

protocol=udp

/ip firewall mangle add action=mark-routing chain=output \

connection-mark=dns new-routing-mark=route-to-modem1 passthrough=no

Seperti gambar di bawah ini:

• Kemudian buat Routing BackUp,gunanya bila di antara 3 modem tersebut ada sebuah modem yang nggak konek maka semua koneksi akan melewati gateway yang masih konek internet,perintahnya:

/ip route add check-gateway=ping dst-address=0.0.0.0/0 gateway=192.168.11.1 \

routing-mark=route-to-modem1 distance=1

/ip route add check-gateway=ping \

dst-address=0.0.0.0/0 gateway=192.168.12.1 routing-mark=route-to-modem1 \

distance=2

/ip route add check-gateway=ping dst-address=0.0.0.0/0 \

gateway=192.168.13.1 routing-mark=route-to-modem1 distance=3

/ip route add \

check-gateway=ping dst-address=0.0.0.0/0 gateway=192.168.12.1 \

routing-mark=route-to-modem2 distance=1

/ip route add check-gateway=ping \

dst-address=0.0.0.0/0 gateway=192.168.11.1 routing-mark=route-to-modem2 \

distance=2

/ip route add check-gateway=ping dst-address=0.0.0.0/0 \

gateway=192.168.11.1 routing-mark=route-to-modem2 distance=3

Seperti gambar di bawah ini:
