Good day
I have setup load balancing with the following.

WAN 4 is no longer in use. I am able to reach the combined speeds of the 3 internet connections with a torrent program. However I am curious as to why WAN 2 and WAN 3 are not in Active state. In winbox they just appear blue as if unreachable.
Please may someone assist with a possible reason and check over my code. as far as i can see it is adequate.
