Your rules are essentially the same as mine and I don't see how it that different, maybe I am just missed the point. The reason you see many more rules than is needed because I want to make them the connection symmetric so that it does not matter which ethX is the upstream, and which is the down stream, ie whichever port you plug into it will still work. And I have specifically confirmed that the other two additional rules have no traffic.
