I doubt that all of those Port opening an NAT stuff will help anything. As far as I know that was Bungies suggestion to deal with the centipede error (correct me if I'm wrong here).
That means all other errors such as bee, lion, hare etc must have other origins. Otherwise Bungie wouldn't have made the suggestion only for that specific error.

I had bee and those ports fixed it for me. It's worth trying if you're having problems. Back when WoW was released I had the same problems with ports, so it's possible.
