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.

can anyone help with this pls :S

Because you are using the routes with routing marks and not the routes with the higher distance. It sounds like it is working right.

Yes. It seems to be an ISP issue. the DSL lines give issues at random between each other. If say one connection is timing out, will the router still choose that path? is there a way to make the router check if the connection is stable or not and cut it off till it stabilizes?

Thanks in advance.
