Load Balancing nth buat Mikrotik Ver 3.xx dan 2.9xx
Sebelumnya saya minta maaf dulu yach kalo seandainya REPOST

cara load balancing atau pun cara mengabungkan 2 line speedy.
disini saya ingin membagikan contoh load balancing nth yang saya pakai di server saya

berikut contohnya buat mikrotik versi 3.xx  :

Ip Modem 01 : 192.168.1.1 interface=speedy1
IP Modem 02 : 192.168.2.1 interface=speedy2
IP Local : 10.18.92.1 interface=Local

Setting Buat Mangle

/ip firewall mangle
add chain=prerouting action=mark-connection new-connection-mark=speedy-1
passthrough=yes connection-state=new in-interface=Local nth=2,1 comment="" disabled=no

add chain=prerouting action=mark-routing new-routing-mark=speedy-1 passthrough=no
in-interface=Local connection-mark=speedy-1 comment="" disabled=no
 
add chain=prerouting action=mark-connection new-connection-mark=speedy-2
passthrough=yes connection-state=new in-interface=Local nth=1,1 comment="" disabled=no

add chain=prerouting action=mark-routing new-routing-mark=speedy-2 passthrough=no
in-interface=Local connection-mark=speedy-2 comment="" disabled=no

Setting NAT

/ip firewall nat
add chain=srcnat action=masquerade out-interface=speedy1
add chain=srcnat action=masquerade out-interface=speedy2
add chain=srcnat action=masquerade src-address="10.18.92.0/24"

Setting Routenya

/ ip route
add dst-address=0.0.0.0/0 gateway=192.168.1.1 scope=255 target-scope=10
routing-mark=speedy-1 comment="" disabled=no

add dst-address=0.0.0.0/0 gateway=192.168.2.1 scope=255 target-scope=10
routing-mark=speedy-2 comment="" disabled=no
 
add dst-address=0.0.0.0/0 gateway=192.168.1.1 scope=255 target-scope=10
comment="primary connection" disabled=no

Berikut scripting Load Balancing dengan konfigurasi 2 Line untuk Mikrotik versi 2.9.27
Sesuaikan IP masing-masing interface menurut network kita.

Note : 10.11.90.1 = IP Local
192.168.1.1 = IP Modem Speedy 1
192.168.2.1 = IP Modem Speedy 2

/ ip address
add address=10.11.90.1/24 network=10.11.90.0 broadcast=10.11.90.255
