From your first post:
when I connect a client to opt1 i can not reach internet
I can not understand where is the problem. How can I create multi lan correctly?
And from your last post:
In that configuration I have no problem.
I'm not going to try to tell you that you have a problem or not, but you did say so at one point, even if you're backtracking now. In any case, your setup is technically flawed in that you have overlapping subnets on your router interfaces.
