[Hi,
Please Explain me how to configure Load Balancing between 2 WAN.

I am searching for the solutions.

here is the example

http://wiki.mikrotik.com/wiki/Improved_Load_Balancing_over_Multiple_Gateways

you will need to change the following example for 3 gateway configuration.
‘nth’ configuration for 3 lines is the following,
2,4,0
2,4,1
2,4,2

how to speed bandwith if 2 WAN merge?
