When we want to make Loadbalancing system used Mikrotik 2.9.x, we can using the rule from here. But there is little different with Mikrotik 3.x
Ok then, let’s started, i will use 5 connection here.

Explanation
First we give a code snippet and then explain what it actually does.
IP Address and Mangle
/ ip address add address=192.168.0.1/24 network=192.168.0.0 broadcast=192.168.0.255 interface=Local comment=”” disabled=no
/ ip address add address=10.111.0.2/30 network=10.111.0.0 broadcast=10.111.0.3 interface=Uplink1 comment=”” disabled=no
/ ip address add address=10.112.0.2/30 network=10.112.0.0 broadcast=10.112.0.3 interface=Uplink2 comment=”” disabled=no
/ ip address add address=10.113.0.2/30 network=10.113.0.0 broadcast=10.113.0.3 interface=Uplink3 comment=”” disabled=no
/ ip address add address=10.114.0.2/30 network=10.114.0.0 broadcast=10.114.0.3 interface=Uplink4 comment=”” disabled=no
/ ip address add address=10.115.0.2/30 network=10.115.0.0 broadcast=10.115.0.3 interface=Uplink5 comment=”” disabled=no
The router has 5 upstream (WAN) interfaces with the addresses of 10.111.0.2/30; 10.112.0.2/24; 10.113.0.2/30; 10.114.0.2/24 and 10.115.0.2/30. The LAN interface has the name “Local” and IP address of 192.168.0.1/24.
For the ip firewall mangle, 5 uplink connection need 5 connection mark and 5 routing mark.
Mangle 1 : nth : 5,1
Mangle 2 : nth : 4,1
Mangle 3 : nth : 3,1
Mangle 4 : nth : 2,1
Mangle 5 : No nth
Here the explanation :
Mangle 1 : read all traffic and match 1/5 of traffic
Mangle 2 : read 4/5 traffic and match 1/4 of they traffic (1/5 total traffic)
Mangle 3 : read 3/4 from 4/5 traffic above (or 3/5 total traffic) and match 1/2 traffic above (1/5 total traffic)
Mangle 4 : read 2/3 from 3/5 total traffic (or 2/5 total traffic) and match 1/2 traffic above (1/5 total traffic)
Mengle 5 : read the rest of traffic (1/5 total traffic)
Thats it. Now you can try your setting.
Happy Surfing with 5 Connection.. 🙂
