bandwidth control through 3 interfaces

Hi,

I have 3 lines adsl with three different ISP, each of these lines is connected to a different (ether1, ether2,ether3) ethernet on the mikrotik. I would like that the clients connected to the fourth (ether4) interface of the mikrotik has access to internet through one of the three lines adsl according to the congestion.

Do you know how to point out me as I have to act?
thanks,
Felice

Is the capacity of all three links equal, or are they unequal.

thanks for the interst,

the capacity is unequal…

You can do some policy routing, traffic marking and proritize links based on capacity. There is an example in in the manual that can be edit to your needs.
