Thanks Rubens for your reply. I was playing around with a spare rb433 doing something similar to what you just posted (nth+conn-mark rules) but, things were not working properly. I noticed my connections were really really slow, I don't know if I did something wrong. One other thing, how about fail over? If one line goes out would the other 3 work and that other line would be ignored until is back up? How can that be done? I would also love to prioritize traffic, SYN ACK flags and DNS be on the highest priority, etc... I know is too much but, would like to do something like that, I don't know if all these are doable at the same time.
